How can I get Excel to work with multiple users?

Episode 1044 (2:21:35)

Pablo from Los Angeles, CA

Pablo wants to have a single spreadsheet that can be accessed by multiple people. Leo says that's tough because Excel doesn't know which version to save and which to ignore. Google Docs is a good option because it offers version locking.

Office 365 is Microsoft's new online version and Excel can work that way. He can buy the Personal or Business version.
