Google Docs and Microsoft Excel are both powerful spreadsheet programs that allow users to store and manipulate data. Google Docs enables real-time collaboration between multiple users but requires an internet connection. It also has limited features compared to Excel. Microsoft Excel can organize large amounts of data, access tools quickly, store and analyze data flexibly, and be used offline, giving it advantages in security and performance over Google Docs. Overall, Excel beats Google Docs for security where offline data access is possible without network issues.
