What this tool does

Turn a YAML document into indented JSON locally. Inspect syntax errors and review the result before using it in an API or JSON configuration file.

How to use

Paste a YAML document to convert it to formatted JSON.

Features

Parse a YAML document and produce indented JSON for applications that require JSON input.

When to use it

Inspect a YAML configuration as JSON before passing it to an API.

Example and checks

Quote identifiers when leading zeros matter. YAML comments do not appear in JSON, and values outside JSON's data model must be resolved before conversion.

code: "0012"
active: true

{
  "code": "0012",
  "active": true
}

Common questions

Can every YAML value be represented in JSON?

Comments are omitted. Circular aliases and non-JSON values cannot be represented in JSON.
