Why does my YAML fail to convert?

YAML is whitespace-sensitive, so inconsistent indentation or tabs (YAML requires spaces) are the usual culprits. Fix the indentation and the conversion will succeed.

Answer

How to convert YAML to JSON

Convert YAML to valid JSON instantly in your browser. Free, private, nothing uploaded.

Paste your YAML into a YAML-to-JSON converter to get the JSON equivalent. Indented mappings become objects, dash lists become arrays, and the result is standard, parseable JSON.

Input

name: app
port: 8080
debug: true

Output

{
  "name": "app",
  "port": 8080,
  "debug": true
}

Unquoted YAML scalars are inferred as numbers/booleans where appropriate.

Steps

Open the YAML ⇄ JSON tool and set the direction to YAML → JSON.
Paste your YAML into the input box.
Read the formatted JSON output and copy it.
Watch for indentation errors in the source YAML — they are the most common cause of conversion failures.
