This free YAML to CSV converter turns your .yaml files into .csv files. YAML is what configuration is written in now — Docker, Kubernetes, CI pipelines — because it is readable by people as well as machines.
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.
How to convert YAML to CSV

- The conversion starts as soon as the file is read — there is nothing to configure.
- Download each converted file, or pick them up one by one from the list.
What changes when you convert YAML to CSV
CSV is a flat table and YAML can nest. Nested values are written into their cell as JSON text rather than dropped, so nothing is lost, but the result is a table with some structured cells rather than a fully flattened one.
YAML and CSV compared
| YAML | CSV | |
|---|---|---|
| Full name | YAML Ain't Markup Language | Comma-Separated Values |
| Extension | .yaml, .yml | .csv |
| MIME type | application/yaml | text/csv |
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.
CSV: The lowest common denominator for tabular data: every spreadsheet and database reads it. It carries no types, so everything arrives as text, and quoting rules are where most import bugs live.
