"Input string was not in a correct format" when importing bilingual Excel file

I'm trying to import a bilingual Excel file and this appears:

Error message in Trados Studio Task Results window showing 'Input string was not in a correct format.'

Here you can see my file types are in the right order:

Trados Studio Project Settings window with a warning 'Additional unvalidated file types exist.' and a list of file types below.

Is there a problem with the file itself? I tried renaming it, resaving it, assigning a "text" cell format to the English and French columns...
