JSON to YAML

What does JSON to YAML do?

JSON to YAML converts JSON data into clean, readable YAML. Objects become indented keys, arrays become lists with dashes, and strings are quoted only when necessary. If the JSON is invalid, the tool shows the error and where it is.

How to use JSON to YAML

1. Paste your JSON into the left box (an example is loaded).
2. Press Convert.
3. Copy the YAML or download it as a .yaml file.

When is it useful?

• Writing configuration files for Docker, Kubernetes or CI pipelines.
• Making large JSON responses easier for people to read.
• Converting API examples for documentation.

Example

{"server": {"port": 8080, "debug": false}} becomes:
server:
  port: 8080
  debug: false

Good to know

• Conversion runs in your browser; your data is not sent to any server.
• JSON must use double quotes for keys and text values.
• Key order is kept as in your JSON.

Frequently asked questions

Is JSON to YAML free?

Yes. You can use it as often as you like without creating an account.

Is my text sent to your server?

No. JSON to YAML works entirely in your web browser, so what you type or paste stays on your device and is not stored.

Does it work on my phone?

Yes. It runs in any modern browser on a phone, tablet or computer - there is nothing to install.
