I am using Arcmap 10.2 on Windows 7
I joined a shapefile with an Excel file, and the attributes are shown as until I start an edit session. Then, the values are as they should be. They match up by verifying manually the attribute table and the Excel file. I clicked "Save edit" and then ended the edit session, at which point the attributes went back to .
Why is it doing that? How can I fix it?
