How do I convert a YAML file to JSON format online for free?

Upload your .yaml or .yml file above. The converter parses the YAML document and produces a clean, pretty-printed JSON file you can download instantly. No server upload, no login required.

Does the YAML to JSON converter handle YAML anchors and aliases?

Yes. YAML anchors (&anchor) and aliases (*anchor) are resolved during parsing, so the output JSON contains the fully expanded values without any YAML-specific syntax.

Is the JSON output pretty-printed or minified?

Pretty-printed with 2-space indentation by default, making it immediately readable and easy to inspect. If you need a compact version, pass the output through our JSON Minifier tool.

What YAML file extensions are supported — .yaml and .yml?

Both .yaml and .yml are accepted. There is no functional difference between the two extensions; both are conventions for the same file format.

Is the YAML to JSON converter free and private?

Yes — free, no account needed, and your file is processed entirely in your browser.
