No macros on that sheet, also you don't need it in a zip file you can just upload the file, but i am sure the Zip file reduces the size if you are using an older excel.

For those that wish to use a new version of excel you can get a trial copy for free that will last you 6 months, at the end of 6 months you have 3 choices.

1) Continue to use the program and get a popup when opening saying it is unregistered and not be able to update but all functionality is the same.
2) Format your hard drive and re install the program and have it again for 6 months.
3) Purchase the program.

I use option 2 but if i am lazy option 1 is sometimes in effect, has been for the last 2 years.
