biffview for .xlsb??

[drdad5727]

Is there something like biffview for displaying the logical structure of .xlsb files?

Context: I've been asked to adapt some old code that can produce Excel spreadsheets to produce one with more than 64K rows. B-( Am I right that I have to write .xlsb? And that .xlsb doesn't look much like .xls?

Thanks!

Correct

>some old code that can produce
I'm guessing that this knew how to work with BIFF8. Somewhere inside xlsb files you will find BIFF, but it is BIFF12 which is significantly different ...

>to produce one with more than 64K rows
Excel 2007 sheets can have 1048576 rows, so maybe this won't be an issue
