This free TSV to YAML converter turns your .tsv files into .yaml files. TSV avoids CSV's quoting problems by separating on tabs, which matters when the data itself contains commas.
This conversion runs entirely in your browser. The file is never uploaded, which makes it instant, private and usable on work files you would not want to send to a stranger's server.

What changes when you convert TSV to YAML
TSV carries no type information — every value is text. Numbers and booleans that look like numbers and booleans are converted to real types, which is almost always what you want and occasionally not, for example with leading-zero identifiers and postal codes.
TSV and YAML compared
| TSV | YAML | |
|---|---|---|
| Full name | Tab-Separated Values | YAML Ain't Markup Language |
| Extension | .tsv | .yaml, .yml |
| MIME type | text/tab-separated-values | application/yaml |
TSV: CSV with tabs instead of commas, which sidesteps the quoting problem when your data contains commas. Common in bioinformatics and when exporting from databases.
YAML: A human-readable superset of JSON used for configuration almost everywhere — Docker, Kubernetes, CI pipelines. Indentation is significant, which is both the appeal and the usual source of errors.
