{ } How to use

Paste your JSON.
Select Process to convert it to YAML.
Copy the YAML, or download it as a .yaml file.

{ } How it works

JSON to YAML works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Input

JSON input — paste or type your input in the left panel (use Sample for an example)

Output

YAML text — copy or download it from the Output panel.

{ } Common uses

Move an API payload into a Kubernetes, Docker Compose or CI configuration.
Hand a configuration to people who find YAML easier to read and edit.
Review a large document without closing brackets and quotation marks in the way.

{ } Limitations

The output is indented with two spaces, and lines are never wrapped — a long string stays on one line.
No comments are produced, because JSON has none to carry over.
Anchors and aliases are not generated, so a value that repeats in the input repeats in the output.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Is the YAML equivalent to my JSON?

Yes. YAML is a superset of JSON, so every value converts without loss.

Can I convert it back?

Yes. YAML to JSON returns the same structure.
