Custom number formats

[Guest]

How do I fix the message "no more custom number formats can be added" during Excel startup?

Oskar,

Below is a post from Leo Heuser that shows how to delete unused custom
numberformats.

Unfortunately Excel doesn't have an object for numberformats, so I had to
find another way of dealing with the problem. The below
routine will do the job.
A new sheet is inserted in the workbook and all custom numberformats are
entered in column A.
Column B contains a list of all numberformats used in the workbook and
finally column C lists all numberformats not used in the
book.
I'm not particularly happy with the flashing dialog, but OTOH it seems to
work, and I don't have to fiddle with parsing binary
files to "guess" how the custom number formats are saved.
If you have hundreds of custom formats (I don't know, if there is a limit to
the number), the routine might take a couple of
minutes, but OTTH the cleansing isn't made every or every other day.
Let me know how it works out, as I haven't tried it on a really large number
of formats.
The routine will not work on the Mac-version.

Best regards
