Frequently asked questions
How do I copy Excel data as TSV?
Select the cells and copy: the clipboard already holds TSV. Paste it here and get your CSV.
What about fields containing commas?
They are quoted automatically so the CSV stays valid.
Are line breaks inside a cell supported?
Yes, as long as the cell is quoted they are preserved inside the quotes.
Can I output semicolons instead of commas?
Output uses standard commas. If your program expects semicolons, most let you pick the separator on import.
