What the TSV converter writes
TSV uses tab characters between fields instead of commas. Fields containing tabs, quotes, or line breaks remain quoted, and formula-like values receive a leading apostrophe for safer spreadsheet opening.
The same 50 MB CSV input limit and production parser used by the viewer apply here. The generated file is created only after parsing succeeds.
Plain answers
TSV conversion questions
Is this a real TSV file?+
Yes. The download is valid TSV text created from the parsed CSV table.
Is my CSV uploaded?+
No. The selected file is read and converted in this browser tab. Loading the page, code, or bundled sample still makes ordinary web requests.
What happens to data types?+
All source cells remain strings. This preserves identifiers and leading zeroes and avoids guessing that a date, boolean, or formula-like value has another meaning.
