Convert JSON to YAML, directly in your browser — a common need when writing configuration files.
Your JSON is processed locally in your browser and is not uploaded to our server.
FAQ
Is my JSON uploaded anywhere?
No. The conversion happens entirely in your browser using JavaScript. Your data is never sent to our server.
Does the YAML output preserve number and boolean types?
Yes — unlike XML, YAML has native support for numbers, booleans, and null, so JSON’s types are preserved exactly.
Why are some strings quoted in the output and others not?
A string is quoted only when it needs to be — for example, if it looks like a number, a boolean, or contains a colon — to keep the resulting YAML both correct and easy to read.
