Let’s discuss some common scenarios which may lead to corrupt MS Office 2016 files:

Scenarios behind Microsoft Office Files Corruption

Scenario 1 – Disruption during Data Migration

The Recover Unsaved Workbooks option allows you to restore the Excel file that you forgot to save before closing MS Excel or it stopped working. The steps are as follows:

• Navigate to ‘_File > Open._’
• Scroll to the bottom and click on ‘Recover Unsaved Workbooks.’ This opens a File Explorer browser window.

• Now look for the Excel file that you lost and then double-click on it to open and restore the Excel file.
• Once the file is open, click on File > Save As and save it to your desired location.

However, this option works only if you had enabled and set up the ‘Save AutoRecover information every X minutes_’ option and enabled the ‘_Keep the last AutoRecovered version if I close without saving’ option.  

Also, this may not restore the most recent copy of your Excel file, but it will surely save your time that went into creating and editing the workbook.

2. Repair and Restore Corrupt or Inaccessible Excel File

If the Excel file you are trying to open or access is corrupt, MS Excel will display an error message. When MS Excel detects corruption, it starts ‘File Recovery Mode’ to repair the Excel workbook.

However, if it doesn’t start automatically, you can manually repair minor corruption error and restore the Excel file by following these steps:

• Navigate to File > Open and then navigate to the corrupt or damaged Excel file location.
• Select the file and then click on the arrow beside the ‘Open’ button to choose the ‘Open and Repair…’ option.

• Now click ‘Repair’ if you want to recover maximum data from a corrupt or inaccessible Excel workbook and restore it to a new Excel file.

If the ‘Repair’ option fails, use the Extract Data option that extracts values, data, and formulas from the Excel workbook.

3. Revert Excel File to Last Saved Version

When an Excel file gets corrupt or damaged while working, you may revert the Excel file to the last saved version. This allows you to restore the Excel file version that isn’t corrupt or damaged. The steps are as follows,

• Click File > Open.
• Double-click the name of the workbook that you have opened in Excel.
• Click Yes to reopen the workbook.

The workbook opens without any changes you’ve made that might have caused the workbook to become corrupted.
