I work with a Excel Spreadsheet on a daily basis - it contains basic formulas and sums. Over the last couple of months it has been gradually growing (not physically as it generally stays the same size)

It got to 19.4 mb in size whem really it should be around 500kb

We cant work out why it has done this and where it is storing this extra information

It has basically become unusable as it is so slow

Anyone have any ideas?
