How to use YAML to CSV

Get the best out of YAML to CSV: every option explained, a worked example, and what to check when the output is not what you expected.

Updated July 31, 2026

What it does

Convert flat or nested YAML arrays directly into tabular downloadable CSV lists. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

OptionTypeDefaultWhat it does
yamltextYAML resolving to an array of objects (or a single object). Required.

Worked example

Run these settings on the tool page:

  • yaml: name: Alice

You get:

"name"
"Alice"

Troubleshooting

  • Nothing happens / the output stays empty. yaml is required — the tool waits until you provide it.
  • It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.

Bash
curl "https://api.toolsxpo.com/v1/yaml-to-csv" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
