How to Use This Tool

Convert CSV into TSV (tab-separated values) using a real CSV parser and serializer. This avoids corrupting data when fields contain commas, quotes, or line breaks.

The tool is intentionally minimal: no TSV output formatting options are needed for most cases. It focuses on correct parsing, clean TSV output, and copy/save convenience.

  1. Step 1 — Paste CSV, drop a file, or fetch a CSV URL.
  2. Step 2 — Adjust parsing options like delimiter, quote character, headers, and empty-line handling.
  3. Step 3 — Copy or save the TSV output (.tsv).

FAQ

3 questions
Is this just replacing commas with tabs?
No. The tool parses CSV first, then re-serializes it as TSV. That preserves quoted commas, embedded newlines, and escaped quotes correctly.
Does the converter upload my file?
No. The conversion runs in your browser. Your data stays on your device unless you choose to fetch a remote URL directly from your browser.
Why is there a header row option?
It controls whether the first row is treated as column names during parsing and re-export. This helps preserve the intended structure when rows are uneven or when you want the first row treated as data.
