Hi Thomas,

The last place it was publicly documented was in the Excel 97 SDK, which
is now out of print. You might be able to find a copy from a used book
seller. The only other alternative is to write Microsoft and ask them for a
copy. Here's the text regarding this option from KB article Q239653:

Hi there,
is the binary file format of Excel-files documented (it surely is -
somewhere), and is this documentation available anywhere? I tried to
google
for it but wasn't lucky. I'd like to generate Excel files outside of
Excel.
TIA
Thomas

Thank you Rob,
that's what I was looking for!
