Save out as a TAB file, then run it through Avid Log Exchange which takes in TAB and export ALE. Or you can add the global header from another ALE into the file.
Top Row are column names but must match Avid's uppercase/lowercase exactly. I would suggest exporting a TAB from MC and using that as a template. Also make sure the exported or save-as TAB file has proper "returns" after each clip data's entry. Especially the last line in the file.
