What is the difference between JSON and YAML?

JSON uses braces {} and brackets [] with strict quotation requirements, while YAML uses indentation for structure. YAML is more human-readable and supports comments, making it preferred for configuration files. JSON is better for data interchange between applications due to its strict format.

Is this JSON to YAML converter free?

Yes, our JSON to YAML converter is completely free with no usage limits. There's no signup required, and your data is processed entirely in your browser without being sent to any server.

Can I convert YAML back to JSON?

Yes! Use our YAML to JSON converter at /yaml-to-json for reverse conversion. Both tools work instantly in your browser.

Does the converter preserve data types?

Yes, our converter accurately preserves all JSON data types including strings, numbers, booleans, null values, nested objects, and arrays in the YAML output.

Can I use this for OpenAPI/Swagger files?

Absolutely. Our converter handles OpenAPI 3.0 and Swagger 2.0 specification files, properly converting the entire API definition structure to YAML format.

Is my data secure when using this converter?

Yes. All conversion happens locally in your browser using JavaScript. Your JSON data is never sent to any server or stored anywhere. Your data remains completely private.

What if my JSON has errors?

The converter validates your JSON before conversion. You'll see a clear error message identifying the problem, such as missing commas, unmatched brackets, or invalid characters.

Can I convert large JSON files?

Yes. The converter runs in your browser and can handle files as large as your browser's memory allows. For extremely large files, consider using command-line tools like yq or jq.

Does the output preserve key order?

Yes. The converter maintains the same key order from your original JSON. Keys appear in the YAML output in the same sequence you provided them.

What indentation does the YAML output use?

The default output uses 2-space indentation, which is the most common YAML style. You can change this to 4 spaces if your project requires it.

How to Convert JSON to .drone.yml

Paste your pipeline JSON

Drop in the JSON describing your kind, type, and pipeline steps.

Get .drone.yml

Valid Drone CI YAML appears instantly, with steps correctly structured.

Commit to your repo

Copy or download the file, save it as .drone.yml, and push to trigger the pipeline.

Why Drone CI Uses YAML

Drone pipelines are defined in .drone.yml at the repository root, describing the pipeline kind, steps, and the conditions that trigger them.

Pipeline definitions generated by tooling often start as JSON. Converting to YAML yields a .drone.yml Drone can parse directly.

Benefits for Drone Pipelines

Pipeline-Ready

Output is valid .drone.yml syntax. Commit it to your repo root and the next push runs the pipeline.

Readable Steps

Step order and commands are far clearer in YAML than in nested JSON during review.

Comment Your Config

Document why a step has a when condition or specific image. YAML supports # comments; JSON does not.

Private Processing

Pipelines reference secrets. Conversion is local to your browser, so nothing sensitive is uploaded.

Frequently Asked Questions

Will the YAML run as a Drone pipeline?

Yes, provided your JSON matches Drone structure (kind, type, steps). Save it as .drone.yml at the repo root and Drone will run it.

Are multiple pipelines supported?

Drone supports multiple pipeline documents in one file separated by ---. Convert each pipeline's JSON and join them with the document separator.

How are step commands handled?

A step's commands array converts to a YAML list of shell commands, exactly what Drone expects.

Why are some values quoted?

YAML quotes values that could be misread, such as branch filters or image tags. Drone interprets the quoted values correctly.

Is my pipeline config private?

Completely. Conversion runs in your browser, so secret references never leave your machine.
