So, I have a spreadsheet with a column of barcodes that should be 6 digits long, like this A02938 (a letter with 5 numbers after it), but sometimes another digit is added by mistake, turning it into something like this A024938. So, my question is this...

How can I highlight the cell if it contains more than 6 digits?

Thanks for your help.

1. Go to Format > Conditional Formatting
2. In apply to range select the column where you have the barcodes. For example (A:A)
3. In format rules, select the dropdown-menu option Custom formula is and add =LEN(A:A) > 6
4. Choose the formatting style you prefer below
