I was wondering if there is a limit on the size of file you can have in Excel.

I have built a file with multiple calculations that is now starting to show signs of strain.

Sometimes when I am working on data in a cell and then click on another cell, Excel hangs up and will sometimes display "not responding" across the top bar of the window.

It eventually catches up, but I want to make sure I don't crash the file after entering all the data that I am keeping track of.

The file size is 1.01 MB.
