JSON to YAML

How to convert JSON to YAML

1. Paste your JSON in the left box.
2. The YAML version appears on the right as you type.
3. If the JSON is broken, a message tells you where.
4. Press Copy YAML.

Why convert JSON to YAML

JSON is everywhere, but it is noisy to read, with braces and quotes on every line. YAML shows the same data using indentation instead, which is calmer to scan and to edit by hand. People often pull JSON from an API, then turn it into YAML for a config file they will maintain.

What changes and what stays

The data does not change. Only the way it looks does. Braces and most quotes disappear, and nesting is shown by indentation. YAML is a superset of JSON, which means every valid JSON file is already valid YAML; this tool just rewrites it in the cleaner style. Numbers, text, lists, and nested objects all carry across exactly.

Long lines are kept whole

Some converters wrap long text across several lines, which can change how a value reads. This tool keeps each value on one line, so a long URL or sentence stays in one piece and is safe to copy back.

FAQ

Is YAML better than JSON?

Neither is better. JSON is strict and common in APIs. YAML is easier to read and edit, and it allows comments. Pick the one your tool needs.

Will my numbers or true/false values change?

No. A number stays a number and true stays true. Only the layout changes, not the data.

Can I add comments after converting?

Yes. YAML allows comments with #, so you can add notes once the file is in YAML form.

Does key order stay the same?

Yes. The keys keep the order they had in your JSON.

Is my data private?

Yes. The conversion runs in your browser and nothing is sent or saved.

When would I need YAML from JSON?

Config files are the usual reason. Docker, CI pipelines, and many server tools read YAML. Paste JSON from an API or a log and you get the same data as YAML, which is easier to read and to comment.
