About the TSV to CSV Converter

Copy a block of cells out of Excel, Google Sheets or a database client and what lands on your clipboard is tab-separated text. The importer on the other side almost always wants CSV — and wants it quoted correctly, because the moment a value contains a comma an unquoted file falls apart.

Paste the tab-separated text here and get standards-compliant CSV. Fields containing the delimiter, a quote mark or a line break are quoted and their inner quotes doubled, exactly as RFC 4180 requires. Choose comma, semicolon or pipe as the output delimiter, quote only what needs it or every field, and pick LF or CRLF line endings. A UTF-8 BOM can be added so Excel displays accented and Bangla text correctly instead of mojibake.

Key features of the TSV to CSV Converter

Correct quoting

Fields with commas, quotes or line breaks are quoted and inner quotes doubled.

Three delimiters out

Comma, semicolon for European Excel, or pipe.

Excel-safe encoding

An optional UTF-8 BOM stops accented and Bangla text turning into mojibake.

Quote everything on demand

Force quotes around every field when the importer needs values kept as text.

Warns about unsafe output

Turning quoting off when fields contain the delimiter is flagged, not ignored.

Frequently asked questions

When the importer treats unquoted values as numbers and you need them kept as text — reference codes with leading zeros, for example. Otherwise quoting only what needs it keeps the file readable.
