Supported formats and limitations
- Input formats
- CSV
- Output formats
- TSV
- Fields containing a tab, quote or line break use double-quote escaping. The destination must support quoted TSV.
- Formula-like fields get a leading apostrophe. Record separators are written as CRLF.
The converter parses CSV records before writing tabs between fields. Commas inside a quoted field remain data. Tabs, quotes and line breaks use double-quote escaping in the TSV, with CRLF between records. Formula-like values receive a reported leading apostrophe, so those fields change during export.
Maximum input size is 2 MiB per file.

Frequently asked questions
Does a comma inside a field survive the conversion?
Yes. Quoted commas are parsed as part of the field and remain part of its TSV value.
