JSON to YAML Converter

Convert valid JSON objects and arrays into readable YAML.

Local processing

Drop a file here, or paste your data. Maximum 10 MB. Text files must use UTF-8.

Ready when you are.

Your data is processed in your browser and is not stored on our servers.

JSON numbers use JavaScript precision. Quote large identifiers to preserve their digits. Duplicate object keys keep the last value.

What is JSON to YAML Converter?

Convert valid JSON objects and arrays into readable YAML.

The converter writes YAML mappings and sequences from JSON values. It uses a local copy of js-yaml and does not send input to a conversion service.

Why use JSON to YAML Converter?

Use this tool to inspect a small dataset or prepare data for another application without installing software. Processing takes place in this browser. No account is required.

How to use JSON to YAML Converter

  1. Paste your input, upload a file, or load Sample Data.
  2. Choose any applicable options and select Convert.
  3. Review the output, then copy or download it.

Example

Input

{"name":"Ada","roles":["editor","reader"]}

Output

name: Ada
roles:
  - editor
  - reader

Common problems

Strings that resemble booleans or numbers are quoted where needed. JSON cannot represent comments, anchors or custom YAML tags, so these are not generated.

Frequently asked questions

Is my conversion data uploaded?

No. Conversion inputs and outputs remain in this browser. Contact form messages are handled separately by WordPress.

Can I process large files?

The default limit is 10 MB. Browser memory and data complexity can impose lower practical limits.

Do I need an account?

No account is needed to use this tool.
