I just opened a CSV file in LibreOffice, made a small change and hit save, saying "yes, keep using CSV". The file is now filled with tabs instead of commas. My scripts (using Python's CSV lib) won't read it and I have go out of my way to replace tabs with commas.
Just to be clear: a CSV file by very definition uses commas, otherwise it'd be a TSV file, right?
Is there some option in LibreOffice I can set to make it use commas when writing CSV files?
