YAML to JSON

Converts YAML data into JSON for APIs, scripts, and systems that do not accept YAML. It is useful when debugging config values outside their original tool.

Processing

Runs in your browser. Input, settings, and results are not sent to Utilio servers.

What YAML to JSON does

Use YAML to JSON when you need to convert YAML config fragments into JSON for scripts.

When to use it

  • Convert YAML config fragments into JSON for scripts.
  • Inspect nested YAML as a JSON object.
  • Prepare YAML examples for systems that only accept JSON payloads.

How to use it

  1. Paste YAML into the input.
  2. Convert it and read parsing errors if indentation is invalid.
  3. Copy the JSON output into your API client or script.

What to check

  • YAML features such as anchors may not map exactly to simple JSON.
  • Check booleans and numbers after conversion because YAML typing can surprise.

Data, formats, and limits

What stays on your device and what is sent

Runs in your browser. Input, settings, and results are not sent to Utilio servers.

Supported formats

This tool works with typed or generated values rather than uploaded files.

File limits and browser requirements

  • Use an up-to-date browser and check the result on the device where you will use it.

Known limits

  • This tool helps inspect or transform data, but it does not replace code review, security review, or production configuration checks.
  • Do not paste real secrets, tokens, or private keys into data you are not prepared to expose in the browser.

Troubleshooting

  • If validation fails, start with quotes, commas, brackets, whitespace, and input encoding.
  • If the result is unexpectedly empty, check the tool mode and a minimal example without extra fields.
  • Do not paste real tokens, passwords, or keys; use a test snippet with the same format for diagnosis.
