As we mentioned above, this annoying error appears on your screen if you’re trying to copy a large volume of data in your Excel sheets, or if you’re adding formulas to a big number of sheets at once.

The specific reason for this error occurring is hidden in the way Microsoft Excel has been built.

If you select only part of the entire range you need to be filled, and then do the same for the following section of cells.

To make sure that the limitations are not reached, you might want to only select the last row of the previously filled section when you move on to the second, third, etc. segment.

You can repeat this process until you reached the end of your selection need.

2. Separate your Excel file into different workbooks
