There are other programs but you know as well as I do that any time you use
a program to edit a file that wasn't created with that program in the first
place, you're asking for difficulties somewhere done the road.
Maybe, but Excel itself seems to corrupt .XLS files more often than
OpenOffice Calc, or at least Excel proudly reports recovering files
with irritating frequency. When it says it can't recover .XLS files, I
open them in OpenOffice Calc, resave them as .XLS files, then open them
in Excel. At least in the Excel newsgroups, where there are people who
know Excel (warts & all), it's well know that OpenOffice/StarOffice
seem to be more robust than Excel itself when it comes to
opening/recovering .XLS files.
The exceptions are complex formatting and complex array formulas. If
the formatting is minimal but the formulas are complex, better to use
Gnumeric.
