Key notes

  • No one who is using Excel on a daily basis wouldn't want memory errors to occur. 
  • However, this may happen from time to time so updating your Excel app can solve the issue. 
  • You might consider your antivirus program responsible for this scenario as well.
  • If nothing else works, you can try to disable and remove macros or add-ins from your files.

If you work in an organization, you most probably have the latest version of the Microsoft Office suite or Office 365 installed on your PC. Even if you don’t, it’s very unlikely that you have never heard of Microsoft Excel before.

However, this doesn’t make Excel immune to occasional bugs. Such would be the case with an error message users have been reporting, which looks something like this: Out of Memory. Not enough System Resources to Display Completely.

Why does Excel say out of memory?

There is not a single cause for this Excel message to appear, so you should consider a number of reasons. For example, the error may occur because you’re running other consuming apps in the background

Other factors that generate Excel out-of-memory issues are added macros or add-ins included in your sheets.

How do you clear memory in Excel?

The most used and easy solution to clear the memory in Excel is to erase its cache data. In order to do so, you should use the Microsoft Office Upload Center.

You can simply go to Settings and then look for the Delete files from the Office Document Cache when they are closed option. Tick the option and press Delete cached files.

3. Disable your Antivirus

Antivirus software will usually run in the background scanning your Excel file as you make it. This will usually make Excel run out of memory and thus trigger the error message.

Disable your antivirus program and see if Excel still encounters this error. Remember that each antivirus program is disabled in a different way, so check the documentation on the developer’s website for more info.

4. Use the 64-bit version of Excel

The 32-bit version of Microsoft Excel has a is 2 GB limitation. So, if the processes require more than 2 GB, Microsoft excel will run out of memory and the error message will appear.

Moving to the Microsoft Excel 64-bit version provides more space and will thus solve any memory-related issues you may have with the application.

5. Completely reinstall Microsoft Excel

Sometimes we have no choice but to start from scratch. Such would be the case if all the above-mentioned solutions fail to solve your problem.

  1. Remove your old Microsoft Office completely
  2. Go to the Microsoft Office product page
  3. Buy the Office package of your choice
  4. Log in using your Microsoft account credentials
  5. Select Install Now to save the installation file on your PC
  6. Double-click on the downloaded file and follow the on-screen instructions
