Get Rid of corrupt Excel File

Summary: What to do when an Excel file is corrupted? This is a common question that is often asked by Microsoft Excel users. If you too are seeking an answer to this question, read the blog to learn about a few manual workarounds and a specialized Excel file repair tool to resolve the Excel file corruption issue.

An Excel file gets corrupted due to various reasons such as a virus/malware attack, sudden system shutdown when the Excel file is still open, power failure while working with an Excel spreadsheet, etc.

When Microsoft Excel detects corruption in a workbook, it attempts to repair the workbook by starting ‘File Recovery mode’.

Tip! If the file recovery mode doesn’t start, you may use the manual repair process or an Excel repair tool, such as Stellar Repair for Excel to repair a corrupted Excel file. The software can help you quickly retrieve contents from a damaged, corrupt, or inaccessible Excel file and restore the file to its original state.

There even exist a few manual tips that can be used to recover data from damaged MS Office Excel files.

Workarounds to Use When an Excel File is Corrupted

Note: Before carrying out any of the repair and recovery workarounds, it is advised that you must save a backup copy of the damaged file. This is to prevent your files from turning completely inaccessible in case the methods fail to give desired results.

Workaround 1: Use the Open and Repair Method

If MS Excel cannot repair a corrupted workbook automatically, you can try to do it manually. To do so, perform the following:

• Open the corrupt file, like you normally open any file, by clicking File > Open.
• Browse and locate the folder containing the corrupted document.
• When the Open dialog box is displayed:
• Select the Excel document.
• Click on the arrow present to the right side of the Open button and select Open and Repair option.

If this doesn’t help repair the broken Excel file or you encounter  Open and Repair does not work issue, proceed with the next workaround.

Tip! Try an alternative solution, i.e. Stellar Repair for Excel software to repair and recover corrupt Excel files (.xlsx or .xls) when the ‘Open and Repair’ method won’t work.  

Workaround 2: Restore an Excel File with a Shadow Copy

If you’re a Windows 7 or Vista user, you can try restoring the corrupted spreadsheet by using a shadow copy (or a previous version). [Shadow copy](https://en.wikipedia.org/wiki/Shadow_Copy#:~:text=Shadow%20Copy%20(also%20known%20as,the%20Volume%20Shadow%20Copy%20service .) is basically a snapshot (backup copy) of computer files or volumes. The snapshot may contain an older version of your Excel file that has become damaged now. To find out, do the following:

• Launch File Explorer, and right-click the folder in which the file is saved.
• Choose Properties.
• Look for and click the Previous Versions tab. This will display a list of entries under Folder versions or File versions, going back a few days or weeks.
• Double-click one with a date when the file was accessible and could be read. Then, try to open its older version. If it opens, save the older version with a new name and execute the procedure with new file/folder entries.

Figure 2 – Volume Shadow Copy

You would have to repeat the process until you reach the point where the file became damaged. With this, you will get a baseline version of the file, but data may still have been lost.

Workaround 3: Test your Assumptions

If you receive a message saying “Excel file corrupted and cannot be opened”, you would probably believe it. However, there could be other reasons besides corruption that may cause Excel to throw this error message.

Your Office suite, which Excel is a part of, maybe having some primary issues in it causing problems while opening one Excel document. So, try opening another Excel file to check if the problem exists with all the files or just one.

If other Excel documents work correctly, it means that only the particular document is corrupt. On the contrary, if the issue is with your Office suite, repairing the current Office installation may help fix the issue. For this, perform these steps:

• Go to Control Panel and click Uninstall the Program.
• Choose Office.
• Click Change, and hit the Repair button.

You can reinstall the entire Office package. Once reinstalled, try to open the file to check if the issue has been fixed and the Excel file repaired.

Workaround 4: Use Excel File Repair Tool

If the above manual solutions fail, use Excel repair software to successfully repair your damaged Excel workbook and recover all its data. Essentially, the software rebuilds damaged Excel workbook data at a granular level to recover every single object & all the original properties of the workbook.

It is easy to work with Microsoft Excel but sometimes, the application may create issues thereby hampering the smooth functioning of the workbook. One such issue is “unable to Save Excel Workbook”.

Let’s take a look at the issue of Unable to Save Excel Workbook

Instance 1:

In an organization, users connected to one of the servers (Windows 2008 R2) using Citrix – a Terminal Server configured with Windows 2008 R2 –and accessed their data through a File Server, also configured with Windows 2008R2. Since the connectivity to Shared Drive was established through a Terminal server, any conflict amongst the server configuration may create conflict in shared file.

This issue was discussed at length at one of the Tech Forums , where the users were unable to access their workbooks stored on the shared drive. The File menu did not work. As a result, the users were forced to save the workbook by creating quick access shortcuts or locally on the desktop. In many cases, the saving option was ruled out completely.

Instance 2:

A similar problem was reported, wherein the users received an error when saving an Excel workbook after inserting a chart in an existing workbook (previously saved) or copying values from an existing workbook. A system is configured with Windows 7 and Microsoft Office 10 configuration. The issue arises when the user is unable to save the changes after editing in a saved spreadsheet. The following message displays on the screen:

Figure: Unable to Save Excel WorkBook Issue

Further, if the user clicks ‘Continue’, the following error message is received:

“Excel encountered errors during save. However, Excel was able to minimally save your file to <**filename.xlsx**>”.

Note: This issue impacts build Version 1707 (Build 8326.2086) and later, and also only occurs with files that are stored locally, such as on the desktop. This problem does not occur if you manually enter values or insert a chart in a newly created workbook.

Plausible reasons for the ‘Unable to save Excel workbook’ Issue

1. The issue was detected in Microsoft Office Professional Plus 2010 32-bit, Service Pack 14.0.6029.1000.
2. Excel version on the user system may or may not match with Excel version on File server.
3. The issue of ‘Unable to Save Excel Workbook’ impacts only the Build Version 1707 (Build 8326.2086) and later.
4. In case of Issue 2, the problem surfaces when the user adds files, tables or charts in the locally saved excel files, such as on the desktop.

Methods to fix the ‘Unable to Save Excel Workbook’ Issue

There may be an issue with the Build version or the Registry Values settings may not be appropriate, which does not allow the Excel workbooks to save.

But, before starting to resolve the issue, verify the following:

1. The location where the file is to be saved may not have enough space to save the Excel file: Check the available space and save again. You may also use the option of ‘Save As’ to save the file at a new location.
2. Excel file may be a shared one where edits are not allowed by a specific user: There are restrictions attached to documents and other files shared over the network. Check for these restrictions.
3. Antivirus may interrupt in during file saving: Antivirus in the system may not allow saving of the files. Request the system administrator to uninstall the antivirus and reinstall after saving.
4. The file is not saved within 218 characters: If the file is not saved due to the naming issue, then check the character length and try again.
5. Differences in Windows versions of the local system and those on network drive may cause excel not saved issues. Check that all the systems have the same configuration and are updated to the recently available versions.
6. Excel spreadsheet is corrupt: If none of the above factors have not caused hindrance in saving the file, then there may be a probability of corruption in the Excel spreadsheet .

Once verified, look for a healthy and restorable backup. If backup is missing, resolve the issue of “Unable to open Excel File” with manual settings on local system or through a reliable Excel repair software.

Method 1: Modify Registry Entries

1. Upload the unsaved Excel file to Google Docs. Ensure that the file gets converted to Google Sheets format.
2. Check if all the formulae are active and working.
3. Make changes to the Google Sheet and verify that all the changes are working fine.

Conclusion

‘Unable to save Excel file’ is a generic problem that may appear due to various reasons. In this blog post, we presented some of the actual instances reported by users on community forums.

Windows updates, the Build versions, the Service Packs of the local systems and those on the network drive must be either similar or in sync with each other. Any deviation may cause issues in accessing or saving the Microsoft files, as reported in Instance 1 is caused where user is unable to save Microsoft Excel file on the Network Drive. In case, the user is unable to save the file on network drive then the problem lies with the Registry value.

Another case is when the users receive an error while saving an Excel workbook after they insert a chart in an existing workbook or copying values from an existing workbook. This issue is known to affect build Version 1707 (Build 8326.2086) and later, and only occurs with locally stored files.

When a user is unable to save a specific Excel file, then the problem can be resolved using the manual methods or the software based utility. The mode of repair depends upon the level of corruption in Excel file.

Hence, it is suggested to analyze the nature of the problem and decide an appropriate resolution method.

Workaround 1 – Change the Default File Format

By default, an Excel file is saved in .xlsx or .xls file format.

Note: For Excel 2007 and earlier versions, click on the Office button.

• On the left panel, click on Options. 
• In ‘Excel Options’ window, under Save workbooks section, click on the Save files in this file format: drop-down. Select a file format (i.e., the one supported by your Excel version).

• Click OK.

Check if you can open your Excel file. If not, try the next workaround.

Workaround 2 – Edit the Excel File Permissions

You may receive the ‘Excel file format or file extension is not valid’ error if you lack sufficient permissions to open the file. Usually this happens when you try to open an Excel file received from some other user. Follow these steps to change the file permissions and see if it fixes the problem:

• Right-click on the file that won’t open and click Properties.
• In the file properties dialog box, click the Security tab and then hit the Edit button.

• When the file’s permissions dialog box appears, click on the Add button.

• Click on the Advanced button from the ‘Select Users or Groups’ window.

• Select Find Now. A list of all users and groups will get displayed in a search results box. Choose Everyone group from the list and hit OK.

• You can see the ‘Everyone’ group in the ‘Enter the object names to select’ textbox. Click OK once again to return to the file’s permission dialog box.

• Click Everyone from the Group or user names: box and check all the checkboxes under Allow.

• Click on Apply and then OK.

Now try to open the Excel file. If you’re still getting the Excel file cannot open error, use the following workaround.

If the ‘Excel file extension not valid error’ occurs when attempting to open an unsaved workbook, do the following to recover the unsaved workbook:

• In Excel, click File.

Excel will list any unsaved files. Try opening the file and save it. If this doesn’t work, skip to the next workaround.
