Earlier versions of Excel will encounter issues when uploading a SIF file that includes characters with diacritics (e.g. fadas, accents, etc.) as these do not support diacritics.
MS Excel 2010 only has “CommaSeparated Values” – this version will not work, so any diacritics will need to be deleted in order of the SIF to upload successfully.
MS Excel 2019 has “CSV UTF-8(Comma delimited)” – this version will work so diacritics will not need to be deleted.
