Too Many Formats when Sorting

Debi is running into a problem when she tries to sort her worksheet. Instead of doing the sort, she gets a message that says, "Too Many Different Cell Formats."

According to sources at Microsoft, this error occurs when your workbook gets close to exceeding one of the built-in limitations of Excel. A workbook can contain only about 64,000 "custom formats."

Custom formats are unique combinations of formatting attributes, applied to cells. For instance, let's say that you have two cells, both formatted for 10-pt. Arial type. Both use the same number format, and neither of them have borders applied. If you change the font size of one of the cells to 11-pt., then you now have two unique custom formats. If you copy the format of the 11-pt. cell to a third cell, you still have only two custom formats. But if you add a border to one of the 11-pt. cells, you now have three custom formats.

Basically, a custom format is any unique combination of things like typefaces, font sizes, colors, alignment, borders, or other cell attributes. If you have a workbook that has, say, 100 complex worksheets, then it is very possible to get close to the 64,000 custom-format limit.

There is only one way to correct the situation: Reduce the number of custom formats. Select a large block of cells in the workbook, display the Home tab of the ribbon, and then click Clear | Clear Formats (in the Editing group). If Excel won't let you do this even (perhaps you have put the workbook into an unstable state by having way too many custom formats), then you should copy the contents of your worksheets, one by one, to a new workbook. Make sure you use Paste Special to paste only the formulas, so that your formulas are preserved, and you don't copy formatting.

Even though Excel will handle quite a few custom formats, there is one potential "gottcha" that you should keep in mind. If you are creating a workbook that will be used in an older version of Excel (in Excel 2003 or earlier), then the limit on custom formats was only 4,000. You can easily pass that number in the newest versions of Excel, but if you do you won't be able to open the workbook in the older versions of Excel.

Rather than clearing all the formats, you could choose one cell whose format you like, and use either the format painter or Copy + Paste Special to apply that format to all the other cells too. And don't forget hidden sheets/rows/columns!
