Excel users often encounter a typical error message - “Too many different cell formats,” when working on large Excel files. This error prevents you from inserting or modifying rows or columns, or even copying and pasting the content within the same or different workbooks.
This error generally ensues when the number of unique cell formats in the Excel workbook exceed the stipulated limit. The limit defined for different cell format combinations in MS Excel 2003 is 4000, while Excel 2007 and later versions have a limit of 64000 combinations. In this article, you’ll understand more about this Excel error and know the solutions to fix it.
What causes the “Too Many Different Cell Formats” Error in Excel?
Here are some reasons behind the “Too many different cell formats” error:
