I have a spreadsheet that does not allow me to use the autofilter option. The tabs and the information contained therein originated in Excel. I was able to autofilter prior to sending them to another user who also kept them in Excel. The spreadsheets are now back in my hands but autofilter is grayed out and I'm no longer able to use my analysis tools or macros. Can this be fixed?
I searched the web but was unable to find a solution.
