How do you correct this ?

Lots of people seem to run into this problem. Most often the issue is
related to the excessive number of unused and often corrupted styles
and not so much the total count of the cell unique cell format combos.
I wrote a utility to fix XL2007 OOXML files that can be saved down to
XL2003. Here is the link to the blog post:

Requres .Net3.5 and MS Excel 2007. Will fix xlsx or xlsm files.

No need to run the risk of further corrupting your file by using Open
Office like it is suggested on some other forums.
