I am using Excel 2007 and when I save my workbook the total size of workbook getting to large and in such I need to go and save MANUALLY in excel 2003 format.
Sarfraz: How many sheets do you have in the workbook? And how many used rows and columns are in each sheet?
Also, in each sheet, select any cell and push Ctrl + End, and take note of which cell gets selected. This will take you to where Excel thinks your data ends, called the Used Range. Sometimes EXcel gets confused, and thinks your used range extends to the very bottom of the grid.
