Hi Shane Devenshire,
Thank you for reaching out to Microsoft Community Support regarding the memory error you’re experiencing when trying to open an Excel file. I understand how inconvenient this must be, especially since your system resources appear to be more than sufficient. Let’s work through this together to resolve the issue.
Here are a few methods you can try to resolve the issue:
Method 1: Start Excel in Safe Mode Using CTRL Modifier Key
- Click on the Excel icon or your Excel file.
- Hold the CTRL-key and press ENTER. You should not release the CTRL-key. You have to hold it until a confirmation dialog box pops up. Click on the Yes button from the Microsoft Excel dialog box.
- Excel will be opened in safe mode. You can see that Safe Mode is written on your workbook name on the top toolbar.
Method 2: Use Command-Line to Start Excel in Safe Mode
- Click on the Search bar from the Windows Enter run and click on Run from the Best match group.
- The Run window will open. Shortcut keys are Windows + R to open the Run window.
- Enter excel /safe inside the Open text box. Click on OK.
Note: There is a space after the word “excel”. Use the slash (/) after the space. If you don’t use the space, there will be an error in the command.
- Your file will be opened in safe mode. You will see that Safe Mode is written on your workbook name on the top toolbar.
Method 3: Repair the File:
- Open Excel, go to File > Open > Browse
- Select the problematic file, click the arrow next to "Open," and choose Open and Repair.
Method 4: Update Microsoft Excel:
- Ensure you’re using the latest version of Excel. Go to File > Account > Update Options > Update Now (for Microsoft 365 subscribers) or download updates via Windows Update.
Method 5: Clear Excel Temporary Files:
- Temporary files can sometimes cause conflicts. Close Excel and delete the contents of these folders:
- %temp% (press Windows + R, type %temp%, and delete all files).
- C:\Users[YourUsername]\AppData\Local\Microsoft\Office\16.0\OfficeFileCache (replace [YourUsername] with your actual username).
