Understanding the Error
Before we dive into the solutions, it's essential to understand what the "Invalid Excel file extension" error means. This error typically occurs when Excel is unable to recognize the file extension or when the file is corrupted. The error message may vary depending on the version of Excel you're using, but it usually looks something like this: "Excel cannot open the file 'filename.xlsx' because the file format or file extension is not valid."
Method 1: Check the File Extension
Sometimes, the error can be resolved by simply checking the file extension. Here's how:
- Right-click on the file and select "Properties."
- In the Properties window, check the "Type of file" section to ensure it matches the file extension.
- If the file extension is incorrect, rename the file with the correct extension (e.g.,.xlsx,.xls, or.xlsm).
Method 2: Open the File in a Different Version of Excel
If the error persists, try opening the file in a different version of Excel. This can help you determine if the issue is specific to a particular version:
- If you're using Excel 2016 or later, try opening the file in Excel 2013 or earlier.
