About converting JSON to YAML
JSON and YAML represent the same structured data in different styles — JSON is the standard for web APIs, while YAML is the readable choice for configuration. Converting JSON to YAML lets you move data into whichever format the next tool expects without rewriting it by hand.
This page converts JSON to YAML entirely in your browser, parsing and re-serializing locally. Your configs and payloads are never uploaded, queued or stored on a server.
Frequently asked questions
How do I convert JSON to YAML?
Paste your JSON into the box and the YAML appears instantly below, ready to copy.
Is the conversion lossless?
Objects, arrays, strings, numbers, booleans and null convert cleanly. YAML-only features such as comments and anchors have no JSON equivalent.
Can I convert the other way too?
Yes — the converter works both ways; switch the direction toggle to reverse it.
Is my data uploaded?
No. The conversion happens entirely in your browser; nothing is sent to a server.
