When navigating through Microsoft Excel, you receive the error:

There is not enough memory. Please use the 64-bit version of Excel.

The memory error messages can be generic and don't always identify the real cause of the issue. However, if your file is large or contains a large number of features, it is possible you are running low on available memory resources.

It is good to understand Excel's limitations. See the following resources for more information:

• Excel specifications and limits
• Excel 2010 Performance: Performance and Limit Improvements
• Memory usage in the 32-bit edition of Excel 2013 and 2016

There are also several causes outside of resource limitations.

If you are not hitting a resource limitation, please see the Microsoft Support page for this error. It has 8 possible solutions: https://docs.microsoft.com/en-us/office/troubleshoot/excel/available-resources-errors.
