Hi,

Are there any restrictions on the size of an excel file?

I am putting together a large workbook (15 tabs, each with about 1000 lines
in them, with most cells performing lookup calculations), which will
constantly be added to, and (as ever!) its critical that this workbook works
correctly.

Is there any sort of critical limit, or will the workbook just start to get
slower the more it fills up?

Thanks,

Will
