Fix the Too many different cell formats Error in Excel?

Excel has set a limit on the number of unique cell formats within a workbook. Excel 2003 allows up to 4000 different cell format combinations, whereas Excel 2007 and later versions allow a maximum of 64000 combinations. When this limit exceeds, you may encounter errors, such as “Too many different cell formats”. It can prevent you from inserting or modifying workbook rows or columns. Sometimes, it prevents you to copy and paste the content within the same or different workbooks.  This error may also occur due to various other reasons.

You can encounter the “Too many different cell formats” error due to the below reasons:

• Formatting is missing in the workbook.
• Size of your Excel file has increased due to excessive use of complex formatting (conditional formatting).
• Workbook contains a large number of merged cells.
• There are multiple built-in or custom cell styles.
• Excel workbook is corrupted.
