JSON ↔ YAML converter · Guide
YAML to JSON Converter Online
Converting YAML to JSON gives you the format most APIs and programming languages consume natively. Here is how to do it cleanly.
When you need JSON
Many tools, APIs and libraries speak JSON, not YAML. Converting a YAML config to JSON lets you feed it to code or paste it into a request without manual rewriting.
Convert and validate
Paste YAML, pick the YAML-to-JSON direction, and the converter parses and re-serialises it. Invalid YAML — usually an indentation error — is reported so you can correct it.
Frequently asked questions
