JSON to YAML Converter

What is JSON to YAML Converter?

Paste JSON and get the equivalent YAML instantly, useful for converting a config file, API response, or data structure into the more human-readable YAML format used by many CI/CD and infrastructure tools.

How to Use the JSON to YAML Converter

1. 1

   Paste the JSON: Enter a JSON object, array, or config value.

2. 2

   Read the YAML Result Instantly: The equivalent YAML appears automatically as you type.

3. 3

   Copy the Result: Use the copy button to copy the YAML for a CI/CD pipeline or config file.

How the Mapping Works

JSON object keys become YAML keys at the same nesting level, indented two spaces deeper than their parent. Arrays become a list of "- " prefixed items, one per line. Strings, numbers, booleans, and null map directly to YAML's equivalent scalar types, without quotes unless the string needs them (e.g. it contains a colon or starts with a special character).

Example

Input:
{ "name": "Alice", "active": true, "roles": ["admin", "editor"] }

Output:
name: Alice
active: true
roles:
  - admin
  - editor

Each top-level key lines up at the same indentation, and the "roles" array becomes an indented list of "- " items underneath its key.
