About Convert JSON ↔ YAML
JSON ↔ YAML converter overview
Convert JSON ↔ YAML is a developer tool that lets you move between JSON and YAML formats in seconds. This page targets the phrase convert json to yaml online. You paste a JSON or YAML block and the tool returns the same data in the other format. The structure, keys, and values remain intact, so you can switch formats for configs, docs, or tooling without manual edits.
How it works
Paste your data into the input and run the converter. The tool detects the format and outputs the other one. JSON objects become YAML mappings, YAML lists become JSON arrays, and nested structures are preserved. This makes it useful for CI files, infrastructure configs, and any workflow that mixes JSON and YAML. The output is valid and ready to paste into a file or tool.
