om...
I have a really large spreadsheet with loads of formulas (lookups and
vlookups plus mathematical functions) But it takes forever to
recalculate cells whenever I cut and paste or change the contents of
any cell within the workbook...
Are there any formulas that are particularly slow and if so, are there
better ways to perform the same task?
Thanks
