YAML Tools

Format code in JavaScript, TypeScript, JSON, JSON5, HTML, Vue, CSS, SCSS, LESS, Markdown, YAML, GraphQL, XML and SQL. Pick tabs or spaces, set the indent width, and format the input in place with one click.

Convert config and data between JSON, YAML, TOML, JSON5, INI, XML, CSV and .env. Type or paste on the left, pick the output format on the right, and copy the result. Includes a format button and a minify toggle.

Turn docker run commands into a docker-compose.yml, or a compose file back into docker run. Ports, volumes, environment variables, networks, restart policies and resource limits carry over.

Open an OpenAPI or Swagger spec in JSON or YAML and browse it as readable docs. Search endpoints, group them by tag, see parameters, request bodies, responses and schemas with $ref resolved, and copy a ready cURL command for any operation.
