JSON to YAML
Convert a JSON value to readable YAML locally.
JavaScript is required to run the interactive tool. Open the tool separately if it does not load in the frame.
How to use it
Paste valid JSON and press Run. Copy the resulting YAML after checking its values.
Example
An object with name and count properties becomes two YAML mapping entries.
Frequently asked question
Will the output keep the same data?
The converter parses JSON first and serializes that value as YAML.
Limits and privacy
Input is limited to 2 million characters. No schema is checked. JSON numbers are parsed with JavaScript precision, so very large integers can be rounded.
Tool input is processed in a separate browser environment without advertising or analytics scripts. This page does not upload it to the service.
