- Please open your Excel file and click on "file: save as" and select the format "Excel 97-2003 template" for instance.
- Then, just beside the button "save" you will find the option "tools".
- Please click on "tools" and chose "web options"
- Go to the "Encoding" tab
- In the drop-down for Save this document as: choose Unicode (UTF-8)
- Then please click on "Ok" and "save"
Once you will have followed those steps, your document will be ready to use. You will then be able to save this new file in "tab delimited" format and upload it again. The issue with the accents should then be sorted.
