Things got complicated when I received a comma-delimited CSV file from a client in UTF-8 and with the need to deliver a bilingual file. The dilemma was: a) if I was to duplicate the source language (column) by opening the CSV file in Excel and save it again in CSV format, commas were replaced by semicolons, b) if, in exchange, I would try to go saving it in Excel format, by later using the Concatenate function gluing all cells with commas, an additional set of quotation marks would be added when rebuilding the CSV file. Any tips you'd like to share?
