Removing Trailing Spaces from Cells in Entire Spreadsheets

Hi all,

I have an Excel file with several worksheets and each of those worksheets has over 600 rows (a list of employees) and above or under 30 columns. Most of cells have trailing spaces in them and they vary in length. For example:
B5: "Jacobson "
C5: "[email protected] "
(Seems like it's not allowing me to post long gaps between the last letters and the " but I hope you get the idea.)

I'm aware of the TRIM function and know that I could at least get a column or a few copied with the spaces removed. However, it would just take so much time. What would be the most efficient way of getting rid of all the trailing spaces in all the cells in all the columns in all the worksheets?

Works like a charm. Thanks, Olly!
