Guide
JSON to YAML: what it does and how to use it
What this JSON tool does
This converter turns JSON objects and arrays into readable YAML. It helps when you need to move API examples, package configuration, structured data, or generated JSON into documentation or tools that prefer YAML.
How it works
Paste valid JSON and the browser parses it with JSON.parse. The parsed value is then serialized as YAML with consistent indentation. Invalid JSON shows an error, which often points to trailing commas, missing quotes, or unescaped characters.
Examples
- Convert an API response into YAML documentation.
- Turn JSON config into a YAML starter file.
- Create readable examples for README files or internal docs.
Security considerations
Everything runs locally. Do not paste private API responses or secrets into tools on untrusted computers, even when the tool is client-side.
FAQ
Does this preserve JSON key order?
Normal object order is preserved as JavaScript reads it, which is enough for documentation and config examples.
Why did conversion fail?
The input must be valid JSON, with quoted keys and no trailing commas.
Is my JSON uploaded?
No. The conversion runs in the browser only.
