DataNumen Excel Repair: Features, Corrupted Excel File Recovery, XLSX Repair, Pricing, and Alternatives
Excel files can become corrupted for many different reasons, and the problem can be especially serious when a workbook contains financial records, business reports, formulas, customer information, charts, or years of accumulated data. A damaged workbook may refuse to open, display an unreadable-content warning, show missing worksheets, or produce errors when Excel attempts to load it.
DataNumen Excel Repair is a Windows-based Excel file repair and recovery utility designed specifically for damaged or corrupted Excel workbooks. The current DataNumen product page identifies version 4.5, released November 9, 2023, with support for XLS, XLW, XLSX, and XLSM files and Excel versions ranging from Excel 3.0 through Excel 2021, Office 365, and Microsoft 365.
The software is intended to recover workbook data such as worksheets, cells, formulas, shared formulas, array-entered formulas, standard and custom formats, and worksheet names. It also includes a batch-repair function for processing multiple Excel files.
This guide explains DataNumen Excel Repair, how it works, how to repair corrupted XLS and XLSX files, whether an Excel file can be repaired online, how Microsoft’s built-in repair options compare, why Excel files become corrupted, how to save a repaired workbook, and what to do when normal repair methods fail.
What Is DataNumen Excel Repair?
DataNumen Excel Repair is a dedicated Excel recovery program designed to repair corrupted Microsoft Excel workbooks.
Unlike a general file-recovery utility, its purpose is specifically focused on Excel spreadsheet structures. According to DataNumen, the application can repair XLS, XLW, XLSX, and XLSM files created by different generations of Microsoft Excel. The current product information lists compatibility from Excel 3.0 through Excel 2021, Excel for Office 365, and Microsoft 365. (DataNumen)
The software attempts to recover information from damaged workbook structures rather than simply changing the file extension or opening the document in another spreadsheet program.
Its documented recovery targets include:
- Worksheets
- Cell data
- Formulas
- Shared formulas
- Array-entered formulas
- Standard cell formatting
- Custom cell formatting
- Worksheet names
DataNumen also provides batch repair, allowing users to process multiple damaged Excel files instead of repairing every workbook individually. (DataNumen)
This makes the program particularly relevant to users who regularly work with large numbers of Excel workbooks and need a dedicated recovery workflow.
What Excel File Types Does DataNumen Excel Repair Support?
DataNumen Excel Repair currently lists four primary supported file types:
- XLS
- XLW
- XLSX
- XLSM
The product also lists compatibility with Excel versions from Excel 3.0 through Excel 2021, Office 365, and Microsoft 365. (DataNumen)
The distinction between these formats is important.
XLS is the older Excel workbook format associated with earlier generations of Microsoft Excel.
XLSX is the modern XML-based Excel workbook format used by current versions of Excel.
XLSM is an Excel workbook that can contain VBA macros.
XLW is associated with older Excel workspace files.
DataNumen states that XLSM files can be repaired, but there is an important limitation: its current FAQ says the software can recover the data from macro-enabled workbooks but does not recover the macros themselves. The repaired workbook is saved as XLSX. (DataNumen)
Therefore, anyone repairing an important macro-enabled workbook should preserve the original file and understand that VBA code may not be retained by the recovery process.
How Does DataNumen Excel Repair Work?
The basic recovery process is designed to be straightforward.
First, the user opens DataNumen Excel Repair and selects the damaged workbook. The software then analyzes the source file and attempts to recover its usable workbook structures.
DataNumen’s documented workflow allows the user to browse for the source file, enter its name manually, or drag and drop it into the application. The program automatically generates a destination filename, although the user can change the output location or filename. (DataNumen)
After selecting the source and destination, the user starts the repair process.
The application analyzes the workbook and attempts to correct the corruption. A progress indicator displays the current stage and elapsed processing time. After successful recovery, the repaired workbook can be opened in Excel. (DataNumen)
DataNumen recommends closing other applications, including Microsoft Excel, before beginning the recovery process. (DataNumen)
What Can DataNumen Excel Repair Recover?
One of the main reasons users search for a specialized Excel repair program is that an Excel workbook contains much more than plain text.
A spreadsheet can contain hundreds or thousands of cells, formulas, worksheets, formatting information, and other workbook structures.
DataNumen lists several recoverable objects, including worksheets, cells, formulas, shared formulas, array-entered formulas, standard formats, custom formats, and worksheet names. (DataNumen)
This means the software is intended to recover the structure and contents of a workbook rather than simply extracting plain text.
For example, if a workbook contains formulas that calculate totals or percentages, recovery of those formulas can be important because replacing everything with static values may destroy the spreadsheet’s functionality.
However, recovery is not guaranteed for every component. DataNumen specifically states that conditional formatting is not currently supported for recovery. It also states that macros inside XLSM files are not recovered. (DataNumen)
Therefore, the result can depend on the type and severity of corruption.
How Can I Repair a Corrupted Excel File?
There are several approaches to repairing a corrupted Excel file, and it is generally sensible to start with Microsoft’s own built-in recovery feature.
Microsoft Excel has an Open and Repair function. When Excel detects corruption, it can automatically start File Recovery mode and attempt to repair the workbook. If automatic recovery does not start, Microsoft provides a manual process. (Microsoft Support)
The general process is:
- Open Microsoft Excel.
- Select File.
- Select Open.
- Choose Browse.
- Locate the damaged workbook.
- Select the file rather than simply double-clicking it.
- Click the arrow beside the Open button.
- Select Open and Repair.
- Select Repair.
Microsoft also provides an Extract Data option if the standard repair process cannot recover the workbook. This can attempt to extract values and formulas from the damaged file. (Microsoft Support)
If Excel’s built-in repair methods do not recover enough information, a specialized program such as DataNumen Excel Repair is another possible approach.
How to Run a Repair in Excel?
Excel’s built-in repair tool is called Open and Repair.
Microsoft’s current instructions apply to Excel for Microsoft 365, Excel 2024, Excel 2021, Excel 2019, and Excel 2016. (Microsoft Support)
To use it:
- Start Excel.
- Go to File > Open.
- Choose Browse.
- Locate the corrupted workbook.
- Click the workbook once.
- Click the arrow beside Open.
- Choose Open and Repair.
- Select Repair.
If Repair does not recover the workbook, repeat the process and choose Extract Data instead.
The Extract Data option is particularly useful when the workbook itself cannot be completely reconstructed but Excel can still retrieve some values or formulas. (Microsoft Support)
Before experimenting with different repair methods, it is a good practice to make a copy of the damaged file and work on the copy. That protects the original source from accidental changes.
Can I Repair a Corrupted Excel File Online?
Online Excel repair services do exist, but users should be careful when uploading sensitive workbooks.
A spreadsheet may contain financial information, customer details, employee information, passwords, business records, formulas, or confidential company data. Uploading such a workbook to an unknown website can create privacy and security concerns.
DataNumen Excel Repair is a desktop Windows application, not a browser-based repair service. Its current system requirements list Windows and an x86 or x64 Intel-compatible processor. (DataNumen)
For sensitive workbooks, a local repair application can avoid uploading the original file to a third-party server.
If an online repair service is used, users should review its privacy policy, data-retention practices, encryption claims, and file-deletion policy before uploading important information.
For highly confidential business files, local recovery is often the more controlled approach.
How to Repair XLSX Files
XLSX is one of the primary file formats supported by DataNumen Excel Repair.
The process is generally:
- Make a copy of the damaged XLSX file.
- Close Excel and other applications using the workbook.
- Open DataNumen Excel Repair.
- Select the corrupted XLSX file.
- Choose the destination for the repaired file.
- Start the repair process.
- Wait for the analysis and recovery to finish.
- Open the repaired workbook in Excel.
- Check worksheets, formulas, formatting, and important values.
- Save the recovered workbook under a new filename.
DataNumen’s own instructions state that the program can automatically generate a repaired filename, such as a _fixed version of the original filename, and that the output location can be changed. (DataNumen)
The original file should be retained until the repaired copy has been completely checked.
How to Repair XLS Files
Older XLS workbooks can also be repaired with DataNumen Excel Repair.
The current product specification specifically lists XLS support and compatibility with older Excel versions. (DataNumen)
The workflow is essentially the same as XLSX repair:
- Preserve the original XLS file.
- Open the repair application.
- Select the damaged workbook.
- Select an output location.
- Start the repair process.
- Open the repaired copy.
- Verify important worksheets and formulas.
- Save another copy if necessary.
Older XLS files can contain structures that differ from modern XLSX workbooks, so a dedicated Excel recovery tool can be useful when normal Excel opening fails.
Why Are My Excel Files Corrupted?
Excel files can become corrupted for several reasons.
One common cause is an interruption while the workbook is being written to storage. A computer crash, unexpected shutdown, power failure, or application failure can interrupt the save process.
Storage problems can also contribute to corruption. Microsoft specifically notes that damaged files can be associated with situations such as a USB device being disconnected while a file is open. (Microsoft Support)
Network storage can introduce additional problems if the connection fails while Excel is reading or writing the workbook. Microsoft recommends moving a problematic workbook to a local drive when disk or network errors may be involved. (Microsoft Support)
Other potential causes include:
- Failing storage devices
- Unexpected computer shutdowns
- Software crashes
- Network interruptions
- Improperly disconnected external drives
- Damaged sectors
- File-system errors
- Incomplete synchronization
- Conflicts involving third-party applications
- Malware or other unwanted software
- Extremely large or complicated workbooks
Corruption does not necessarily mean that the entire workbook has been destroyed. Sometimes only particular workbook structures are damaged, allowing recovery software to retrieve much of the original data.
How to Open Excel in Repair Mode
If by “repair mode” you mean repairing a corrupted workbook, Excel uses the Open and Repair command rather than a separate application called Excel Repair Mode.
Microsoft explains that Excel can automatically start File Recovery mode when it detects corruption. If that does not happen, users can manually select Open and Repair from the Open dialog. (Microsoft Support)
The important detail is to use the Browse/Open dialog and select the arrow beside the Open button.
Simply double-clicking the damaged workbook may attempt to open it normally instead of using the repair command.
Once Open and Repair appears, select Repair first. If that does not recover the necessary information, try Extract Data. (Microsoft Support)
How to Repair Cells in Excel
There is no universal “repair cell” button because cell problems can have different causes.
If the workbook opens but some cells contain incorrect formulas, missing values, or formatting problems, the problem may be different from file-level corruption.
For a severely damaged workbook, recovery software may attempt to reconstruct cell data and formulas from the underlying workbook structure.
DataNumen specifically lists cell data, formulas, shared formulas, array-entered formulas, and cell formatting among its recovery targets. (DataNumen)
If the workbook opens normally but only a few cells are incorrect, manual correction may be more appropriate than using a complete file-repair program.
If the workbook cannot open at all, the problem is more likely to require a workbook-level recovery approach.
How to Start Office Repair
Sometimes the problem is not the Excel file. The Excel application itself may be damaged.
Microsoft provides Quick Repair and Online Repair for supported Microsoft 365 and Office installations on Windows. The repair process is accessed through the installed Office product’s modification options. (Microsoft Support)
On Windows 11, the general procedure is:
- Open Settings.
- Go to Apps.
- Open Installed apps.
- Find Microsoft 365 or Office.
- Open its additional options.
- Select Modify.
- Choose the appropriate repair option.
Microsoft explains that Quick Repair replaces corrupted files, while Online Repair performs a more comprehensive repair of the Office installation. (Microsoft Support)
This type of repair fixes the Office installation, not necessarily a corrupted XLSX or XLS workbook.
That distinction is important.
If Excel itself will not launch correctly, Office repair may help. If Excel launches normally but one specific workbook refuses to open, the workbook may require Open and Repair or file-recovery software.
Can I Repair a Corrupted Word File Online?
Word files are different from Excel workbooks, but Microsoft Office provides similar recovery concepts for damaged Office documents.
Microsoft’s general damaged-document guidance says that Word, Excel, and PowerPoint can sometimes use the Open and Repair command to recover a damaged document. (Microsoft Support)
For a corrupted Word document, users can try:
- Open Word.
- Select File > Open > Browse.
- Locate the damaged document.
- Select it.
- Click the arrow beside Open.
- Select Open and Repair.
Third-party online Word repair services may also exist, but sensitive documents should not be uploaded without checking the provider’s privacy and security practices.
DataNumen also provides a separate DataNumen Word Repair product rather than using Excel Repair to repair Word documents. Its current order page lists DataNumen Word Repair separately from DataNumen Excel Repair. (DataNumen)
How to Repair an Excel Install
If Excel itself is malfunctioning, repairing the Office installation can be more appropriate than repairing individual files.
Microsoft’s current Office repair instructions support both Quick Repair and Online Repair for supported Windows installations. (Microsoft Support)
Quick Repair is designed to replace corrupted Office files without requiring the full online repair process.
Online Repair is more comprehensive and can reinstall or repair more components of the Office installation. Microsoft notes that Online Repair requires an active internet connection. (Microsoft Support)
After repairing Office, restart the computer and test Excel again.
If Excel now works correctly with other workbooks but one particular file remains corrupted, the problem is probably associated with that workbook rather than the Office installation.
How to Save an Excel Repaired File
Saving a repaired workbook correctly is important because you do not want to overwrite the only copy of your damaged file.
DataNumen’s repair process allows the user to select the destination file and output location. The application can automatically generate a repaired filename, which can then be opened in Excel. (DataNumen)
A safe workflow is:
- Keep the original corrupted file untouched.
- Repair a copy rather than the only original.
- Save the recovered workbook to a different filename.
- Open the repaired file.
- Check every important worksheet.
- Verify formulas and totals.
- Check formatting where necessary.
- Verify charts and other important objects.
- Save another verified copy.
- Create a backup of the final recovered workbook.
Microsoft also recommends maintaining backup copies and using AutoRecover so that a good version remains available if the primary workbook becomes corrupted.
DataNumen Excel Repair Features
DataNumen Excel Repair includes several features aimed specifically at Excel recovery.
Support for Multiple Excel Formats
It supports XLS, XLW, XLSX, and XLSM files. (DataNumen)
Formula Recovery
The software lists recovery of formulas, including shared and array-entered formulas. (DataNumen)
Cell Data Recovery
Cell contents can be recovered from corrupted workbooks when the underlying information remains accessible. (DataNumen)
Worksheet Recovery
The software can recover worksheet structures and worksheet names. (DataNumen)
Batch Repair
DataNumen provides a batch-repair function for processing multiple Excel files. Its comparison information lists batch repair as one of its features. (DataNumen)
Simple Interface
The product interface is built around selecting a source file, choosing an output location, and starting the recovery process. (DataNumen)
DataNumen Excel Repair Limitations
No recovery application can guarantee that every damaged workbook will be restored perfectly.
DataNumen’s own documentation identifies some limitations.
For example, its FAQ states that conditional formatting is not currently supported for recovery. (DataNumen)
For XLSM files, the software can recover the workbook’s data but does not recover VBA macros; the repaired output is saved as XLSX. (DataNumen)
The program is also Windows-only according to its current requirements. Although it can repair workbook files generated by Excel for Windows and Mac, the recovery software itself requires Windows. (DataNumen)
The current listed version is 4.5, with a release date of November 9, 2023. (DataNumen)
These points should be considered before purchasing the software, particularly if the workbook contains macros or advanced formatting that must be preserved exactly.
Is DataNumen Excel Repair Free?
DataNumen provides a free download/demo version, but the full product is commercial.
The official purchase page currently lists the single-user DataNumen Excel Repair license at $89.95, reduced from a displayed regular price of $129.95 in the current promotion. The same page lists lower per-license prices for larger quantities. (DataNumen)
DataNumen’s broader order page also currently lists DataNumen Excel Repair at $89.95 per single license. (DataNumen)
Because promotional pricing can change, the price shown at checkout may differ from a later price.
Users should also distinguish between downloading the software for free and receiving unlimited recovery functionality for free. A free download does not necessarily mean that the complete commercial recovery capabilities are unrestricted.
Is DataNumen Excel Repair Safe?
DataNumen Excel Repair is a legitimate commercial software product with an official developer site, documentation, licensing information, and support material.
The safest way to obtain it is through the legitimate DataNumen distribution channel rather than modified copies or unofficial software packages.
Users should also understand that repairing a corrupted spreadsheet involves handling potentially sensitive information. Because DataNumen Excel Repair operates as a Windows desktop application, the repair workflow is performed locally rather than requiring the original workbook to be uploaded to a browser-based service. Its current requirements list Windows as the operating system. (DataNumen)
As with any recovery application, users should maintain a backup of the original file before beginning the repair process.
How Much Does DataNumen Excel Repair Cost?
The current official DataNumen Excel Repair purchase page lists:
- 1 license: $89.95 promotional price
- 2–9 licenses: $69.95 each
- 10–24 licenses: $49.95 each
- 25–49 licenses: $39.95 each
- Larger license quantities receive progressively lower per-license pricing.
The displayed standard single-license price before the current promotion is $129.95. (DataNumen)
DataNumen also advertises a 30-day money-back guarantee on its broader order page. (DataNumen)
Pricing and promotions can change, so these figures should be treated as the current listed pricing rather than a permanent price.
DataNumen Excel Repair vs Excel Open and Repair
Microsoft Excel already includes a built-in recovery function, so users do not necessarily need third-party software for every corrupted workbook.
Excel Open and Repair is integrated directly into Microsoft Excel and should generally be one of the first recovery methods to try. Microsoft provides both Repair and Extract Data options. (Microsoft Support)
DataNumen Excel Repair is a dedicated third-party recovery application with additional features such as batch repair and specialized recovery of workbook structures. (DataNumen)
The two approaches can therefore complement each other.
A sensible sequence is to preserve the original file, try Excel’s built-in repair, attempt Extract Data if necessary, and then consider specialized recovery software if the built-in tools cannot recover enough information.
How to Prevent Excel File Corruption
Prevention is often easier than recovery.
Microsoft recommends creating backup copies and configuring AutoRecover. Excel can also maintain recovery information at regular intervals. (Microsoft Support)
Useful practices include:
- Save important workbooks frequently.
- Keep backup copies.
- Use OneDrive or another versioned storage system where appropriate.
- Avoid disconnecting USB storage while Excel is using the file.
- Avoid shutting down the computer while a workbook is being saved.
- Keep Windows and Microsoft Office updated.
- Monitor aging or failing storage devices.
- Avoid editing the same workbook simultaneously through unreliable network connections.
- Keep separate backup copies for important business spreadsheets.
- Test backups periodically.
Microsoft also explains that OneDrive version history can allow users to restore an earlier version of an Excel file when a current version becomes corrupted. (Microsoft Support)
