Hi there,


It seems that workbooks has a habit of accumulating tons of user
numberformats...

Instead of manually deleting the numberformats one by one, is it possible to
write a small macro that will delete all non-builtin user numberformats?


TIA,

An ancient macro. I haven't tested that it does what it claims.

Hi there,

Instead of manually deleting the numberformats one by one, is it possible
to write a small macro that will delete all non-builtin user
numberformats?


TIA,

Try the free "Formats & Styles" excel add-in.
It uses a modified version of the Leo Heuser (rip) code and the screen doesn't flicker.
