Hi Sunil (and Peter) with requested email copy to Sunil,
Slow Response, Memory Problems, and Speeding up Excel
http://www.mvps.org/dmcritchie/excel...sp.htm#formats

which will send you to Leo Heuser's posting ( 2001-05-06 in programming)
http://google.com/groups?selm=OxP9cg...%40tkmsftngp02

Leo's code deletes unused formats, but at the very beginning it indicates
the number of formats and gives you a choice of whether to
continue or not. I would be a good idea to practice on a copy
of your workbook, if you use the full subroutine.

You could put the first part into Auto_Open in a code module
or in Workbook_Open in "Thisworkbook" class module, with
an informative message if over your threshold.

HTH, Please keep discussion in newsgroup, Leo would
be at least as interested in any comments as anyone else.

Is there any way to get a message being displayed when an excel file
reaches 3000 different cell format count?
