Use Application.memoryused to measure the amount of memory being used, and
delete the worksheets one by one, measuring memory each time.
This will give you a good approximation unless you have an unusually high
number of interworksheet links.

Hi, folks,

I like to know which one of the 50 worksheets in my workbook is causing
the size of a few
MB. Is there any VBA method to find that out?

Information about how many cells in each sheet store data
is no help, because of graphic elements in
the sheets.

Regards
Peter
