Excel File Import not setting data type correctly

I am using 5.2.1.10 and am importing workbook that has 4 “Short Date” columns. It imports the first one correctly (Makes it a “Date”) but the other three are coming in as numbers not dates. Any suggestions?

Actions do not set column formats. EasyMorph tries to auto-detect dates using heuristics but sometimes it doesn’t do it correctly. You can set column formats explicitly as explained in this answer: Issue with parsing json and formatting the result - #2 by andrew.rybka
