JSON to YAML

Convert JSON to clean, readable YAML.

YAML to JSON

Runs in your browser — your data never leaves your device.

About the JSON to YAML

Turn JSON into YAML for configuration files, which are easier for people to read and edit. Invalid JSON is reported with the reason.

How to use the JSON to YAML

  1. Paste JSON.
  2. Choose the indentation.
  3. Copy or download the YAML.

How it works

The JSON is parsed and written out with js-yaml (MIT). Strings that could be misread (such as yes, no or numbers in quotes) are quoted automatically.

Examples

  • {"ads":false,"features":["pdf","images"]} → ads: false / features: / - pdf / - images

Frequently asked questions
