Read this post to discover more details about the error, possible causes, and how to rectify the error. To save time & efforts, you can also try an Excel file repair software to resolve the “damage to the file…” error in a few clicks.

When opening a workbook in Microsoft Excel 2003 or later, you may encounter an error message,

“Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted.”

The error message may also occur while exporting an Excel file. Let’s find out what causes this error and what we can do to fix it.

Reasons Behind “Damage to the File Was So Extensive That Repairs Were Not Possible” Error

Your Excel file may be corrupt, oversized, virus-afflicted, etc., which can trigger this error and make the repair impossible. Below are some common reasons.

• Large or oversized excel files hindering export
• Data restore errors
• Field length of a cell is more than 256 characters
• Software conflicts, viruses, network failure
• Unable to open files in upgraded versions
• Errors on output exceeding 64000 rows
• Limited system resources (such as RAM, internal memory)

In a nutshell, the error generally happens if Excel discovers unreadable content, which may also interrupt file saving in Excel.

How to Resolve “Damage to the File Was So Extensive That Repairs Were Not Possible” Error?

Here are a few methods you can follow to fix or resolve the Excel repair error.  

Method 1: Perform Basic Troubleshooting

When opening a corrupt workbook, Microsoft Excel automatically initiates the file recovery mode to repair the corrupt file. However, if it fails to perform automatic recovery, then follow these basic troubleshooting steps:

• This error mainly happens when you try to open the Excel file in an upgraded version.  Try to open the file in an older version of Excel. You might be able to open it.
• Try saving the file with a different file name.
• Use a different file extension to save the file.
• You can save the Excel file as HTML and then open it. However, an HTML file might not save conditional formatting.
• Close other opened applications on the system which may be causing the error.
• Select less data for export at once.
• Delete worksheets if copied from another document; for instance, delete any file or screenshots you have imported.
• Open the file on another system.

If the error persists, then use the manual method to repair a workbook using the below steps:

• Go to the “File” tab.

• Select Open and select the damaged spreadsheet from the Recent Workbooks section on the right, if listed. However, if you cannot find the file in the Recent Workbooks section, click on “Browse” and choose the corrupted workbook.

Sometimes, when you try to export an Excel sheet carrying a huge database, you may face memory errors in older Excel versions like Excel 2003. Here, you’ll have to decrease the amount of data as Excel 2003 does not permit exporting extensive data beyond a limit. However, modern versions such as Excel 2007, 2010 & 2016 allow exporting a large amount of data and utilize more RAM than the older versions.

Following are some other workarounds:

• Use a lesser number of query presentation fields to re-generate the query. Then, again re-enter those fields.
• Decrease the multi-line string field data text up to 8000 characters.

Method 3: Copy Macros and Data to Another Workbook (Empty) in an Advanced Excel version

• Open Excel and go to File > Options.

• Click “**Customize Ribbon.**”

• Look at the right side of the pane and ensure the Developer tab is checked.

• Click OK.

• First, open both the workbooks- the workbook containing the macro and the workbook in which you need to copy the macros.
• Locate the Developer tab.

• Select Visual Basic to display the “Visual Basic Editor.”

  

• Go to the View menu in the Visual Basic Editor.

• Select Project Explorer.

• In the Project Explorer window, drag the module you need to copy to the destination workbook. For example:

Module 1 has been copied from Book2.xlsm to Book1.xlsm

Method 4- Restore the backup file

The workbook backup helps to open the corrupted or mistakenly deleted file. Sometimes, the issue can be fixed using the Recover Unsaved Workbook option in Excel. Here’s the list of steps to recover the files in Microsoft Excel:

How to Fix Excel File Couldn’t Open in Protected View

Summary: This blog discusses about the Excel error ‘The file couldn’t open in Protected View’ and workarounds to fix the error. If you cannot access the Excel file data, using an Excel file repair tool can help you quickly restore the data to its original state.

Protected View is a feature in Microsoft Excel that opens a file in read-only mode while disabling the editing functions. An Excel file opens in Protected View if the file is from an unsafe location. For example, the file may be opened from an insecure Internet location or downloaded as an Outlook attachment from suspicious senders. In that case, your Excel application won’t let you open the file to protect it against malware or virus attacks.

However, the Protected View feature sometimes prevents an Excel file from opening even if it is from a safe location. Also, opening an Excel file may return an error message ‘file couldn’t open in protected view’.

You may be able to resolve the issue by closing all the open Excel files, closing the Excel application, and then re-opening the problematic file. But this process can take a significant amount of time as you need to close and re-open the Excel application and the file continuously.

How to Fix the Excel File Couldn’t Open in Protected View Error?

Here are some workarounds to fix the error:

Workaround 1 – Disable the Protected View Settings

Note: Before disabling the protected view settings, ensure you have a reliable antivirus software installed on your computer to safeguard files against malware or virus attacks.

• Open the Excel file throwing the error, go to File and click the Options tab.
• From the Options dialog box, go to Trust Center and click on Trust Center Settings.
• From the Trust Center Settings dialog box, select the Protected View tab.
• Uncheck the appropriate option under the Protected View section, and then click OK to apply the changes. For instance, uncheck the “Enable Protected View for Outlook attachments” option if the file is a downloaded Outlook attachment.

• Click OK again.

Now try opening the problematic Excel file. If it still doesn’t open, try the following workaround.

Workaround 2 – Repair the Office Installation

Sometimes, corruption in the Office installation may cause Excel to return the ‘file could not open in protected view’ error. So, try repairing your Office installation and check if it solves the problem.

• Open the Control Panel and click the Uninstall a program option under Programs.
• Click Uninstall a program under the Programs tab.
• Right-click the Microsoft Office program you have installed and click the Change button.
• Select the Repair option and click Continue.

Once the repair operation is complete, check if you can open the Excel file without any issue.

Workaround 3 – Install Latest MS Office Updates

Several Excel users have reported about experiencing issues (such as the Protected View issue) on opening an Office document like Excel, Word, or others – after upgrading Windows to a newer version. This problem may occur due to incompatibility between the Office app and the updated Windows version. You can try to fix the problem by upgrading the Office app, and here’s how:

• Click on the File tab in the Excel file that throws an error.
• Click the Account tab at the left-hand bottom of the screen.
• From Office Updates, expand Update Options, and then click Update Now.

After installing the updates, restart your PC and open the Excel file. If this doesn’t work, use the following workaround.

Workaround 4 – Convert the File and Rename It

Some Excel users resolved the ‘Protected view’ issue by renaming their Excel files. But before that, ensure that the file you are trying to open is saved with .xlsx format. If the file type is .xls, you need to convert it to .xlsx format and then rename it. Before converting the file, save a copy of the original file in the desired location.

If the file type is .xlsx, copy the problematic file. Next, open a blank Excel document and paste the copied file. The file will appear as an icon, double-click on it. If it opens without any error, save it with a different name. Hopefully, reaming the Excel file may help resolve the problem.

How to Repair Excel Document on a Flash Drive

Summary: Microsoft Excel files are stored on flash drives if they need to be transferred between systems or if they need to be backed up. But sometimes unforeseen issues can corrupt the Excel sheets stored on flash drives. When that happens, it can be an arduous task to repair Excel documents on a flash drive. Through this post let us try to understand the reasons why Excel sheets stored on flash drives can get corrupted and how users can resolve them easily.

In this digital age, we all work with computers, files, and documents. Flash drives or USBs are common ways of storing data in an external place. Be it for a meeting or for a party playlist, these devices come handy when one wants to transfer data or access the files stored elsewhere.

You may need to access your data from another location. That’s when a USB flash drive might come in handy. And, that’s exactly why Excel sheets too end up on flash drives; either that or for backup purposes. However, there are many instances where an Excel file stored in a USB gets corrupted when one tries to access the file. The error message you get while trying to open the Excel file would be a great clue for figuring out the exact reason behind corruption.

This blog will provide insights into what are the reasons for the corruption of a USB and how the users can repair Excel on flash drive that has been corrupted.

Reasons for USB inaccessibility

Sometimes flash drives or USBs can become unresponsive due to numerous reasons. There are two types of corruption – logical and physical. Physical corruptions occur due to broken stems and connectors, broken circuits, NAND gate, not recognised, RAW, need to format, not accessible, and dead drives (no power supply).

One of the main reasons behind such an error could be that the USB drive has been infected by some virus. This can affect any file – not only the ones which are there in the USB drive but also the ones which are there in the PC/Laptop where you connect the USB drive. It is recommended that you scan the USB drive with reliable antivirus software to detect viruses.

There can be various other reasons that may make your USB corrupt or unresponsive. But there are very slim chances that you will be able to recover a flash drive that has physical damage. However, you can try to run the check disk on the USB drive to fix the drive. We will be discussing this as you read on.

Recovery Methods for Corrupted Flash Drives

There are 3 tried and tested recovery methods. Try them and see which one works out for you.

1. Restoring Excel Files from Windows backup

To bring back your old Excel files, fixing up the corrupt file is your best option. Importantly note that this method would work only if your system’s Windows backup option has been enabled.

Step-by-step process for restoring your older Excel files:

• Connect your USB drive
• Go to “My Computer”->USB Drive->Check if the file exists
• Right click on the excel file and click on the restore previous versions

• You will now see a list of older versions which were created
• Select one the backups and click on “restore”

2. Using Command Line to Recover Excel Files

In case you are looking to repair Excel on flash drive, you can also resolve it by using the command line. Just follow the below steps to see if you can recover the excel files.

• Connect your USB Flash drive
• Open “Run” (press Windows+R) and then open “cmd”

• Type “attrib -h -r -s /s /d (USB Drive Letter):\*.*” where the (USB Drive Letter) is the drive letter you can find using “My Computer”
• Once this has been completed, Windows will start repairing your files
• After the process gets over, try accessing the excel file to see if the data has been recovered

3. Running a “Check Disk” on flash drives

Follow the below steps while the USB flash drive has been plugged into your computer:

• Open “Run” and then open “cmd”
• Type in “chkdsk /X /f (USB Drive Letter)” where the “(USB Drive Letter)” is the letter of the corrupted USB Drive. You can get this letter easily from the “My Computer”.

It will now check your disk to and correct any corrupted records.

What if none of these methods works?

In case none of the above methods works to repair Excel document on a flash drive, then you would need a professional Excel repair software such as Stellar Repair for Excel to restore your files.
