I have a weird situation I've come across.

My workbooks were getting to large in Excel 2010, so I saved it as a binary workbook. This slimmed down the size greatly. BUT now I added one worksheet that is a SQL Query Table. It only has 37 columns and pulls in 60,000 rows.
The workbook increases from 10 mb to 45 mb. What could be causing this massive increase in size? I expect something like this to maybe add 10 mb not 35.

Any ideas to decrease the size of the workbook?
Thanks,
