Excel/trimming size of file


Hi Tom

I am trying to reduce the size of my workbook.  I have:

deleted all of the unnecessary worksheets
taken out all unnecessary formatting
removed unused name ranges

I, however, have some several worksheets that have unused space.  For example I have a worksheet that uses only this range A1:K20.

Is there any value in removing the area that I am using and if so how is this done?

If you go to a sheet and hit F5, then select special and then select last cell.  That shows you want Excel considers to be used in your workbook.  For each cell in the same row and column and to the left of that column and above that row, excel maintains individual information on those cells.  Cells to the right and below are virtual.  To store information, increases the size of the workbook.  So yes, reducing what excel considers as the Used Range will decrease the size of the workbook.  Note that the used range is always a rectangle.  So you can not clear cells here and there and expect any effect.  To reduce you have to select entire rows or entire columns and delete them.  Then save the workbook to effect the change.
