About JSON to YAML conversion
Any valid JSON document — not just arrays — is converted to idiomatic YAML with correct indentation and quoting, ready to paste into your config.
How to convert JSON to YAML
- Drop your JSON files onto the box above, or click Choose files.
- The output format is already set to YAML — adjust it per file if you need something else.
- Click Convert, then download your YAML files (or everything as one ZIP).
Free, no account, no watermarks — and because the conversion runs in your browser, your files are never uploaded to a server.
