file extensions in excel

[Denny Dunn]

I have a coworker that refuses to save excel in the new format (xlsx) I
explained that this format will give her more features than available with
the 2003 (xls) format. Unfortunately I did not know the added features that
saving in xlsx would give. Is there a document out there that gives the
added features in xlsx format?

here's a link that gives the excel 2007 specs. saving in xls format allows
users of older version to open the file, but you lose the features and
limits added to 2007.

Hi,
go to the excel help and in the search area enter xlsx, it will bring an
explanation with all the differences
