YAML to JSON Converter Online
Runs 100% in your browser — your files never leave your device.
Config files live in YAML; APIs speak JSON. Paste your YAML and get clean, two-space-indented JSON out — merge keys are honored, and syntax errors are reported inline instead of silently dropping data. The conversion runs entirely in your browser, so configs with secrets are safe to paste.

- 1
Paste your YAML
The JSON output updates as you type.
- 2

Invalid YAML is flagged inline with the parser message.
