Typically it has to do with your used range getting messed up. As a guess on
one or more of your sheets your scroll bars allow you to drag the scroll
handle well past the end of your data. Here is a link on fixid the used
range...

Hi,
I've created a workbook that captures the daily work done by my team. I had
a similar one before and the new one is more than 11 MB in size. The old one
was less than 1 MB.

To make the changes, i just copied the existing one and formatted according
to the new requirements. I want to know the reason behind huge increase in
the file size...
