“Unable to set the NumberFormat property of the Range class”

Question

This code has been working for ages. I thought maybe I accidently pressed a key but I cannot seem to see it. I suddenly get the error:

Unable to set the Numb

Answer 1

I met with this problem using Fuzzy LookUp AddIn in Office365ProPlus. After I run FuzzyLookUp only 10 rows of output were generated and this message popped up.

Problem was caused by my local setting of Excell.

To fix it I had to change decimal separator from coma into dot under general Excel settings.

On my side it solved the problem perfectly.

Answer 2

The problem as discovered in Chat was the workbook had more than 64,000 formats because of which the user was getting the "Too many different cell formats" error message in Excel

QUOTE from the above link

In Microsoft Excel 2007/2010 files may produce the following error message;

Excel found unreadable content in the file

This problem occurs when the workbook contains more than approximately 4,000 different combinations of cell formats in Excel 2003 or 64,000 in Excel 2007 and higher.
