JSON to YAML Converter
Convert JSON to YAML and YAML to JSON with one switch — free, private, in your browser.
✓ Your files never leave your device. Everything runs locally in your browser.
JSON and YAML describe the same data in different syntax. JSON is best for machines and APIs; YAML is easier for humans and is common in configuration files for Docker, Kubernetes and CI/CD pipelines.
This tool converts both ways in your browser — nothing is uploaded.
How it works
- Paste JSON or YAML – Choose the direction and paste your input.
- Convert – Click Convert to transform the data.
- Copy or download – Copy the result or download it.
Typical uses
- Turning API responses into readable config.
- Converting YAML manifests into JSON for tools that expect JSON.
- Preparing Kubernetes/Docker/CI configuration in the format a tool needs.
Notable differences
YAML allows comments and relies on indentation, while JSON is strict and does not allow comments. Anchors and multi-line scalars exist in YAML but have no direct JSON equivalent.
Frequently asked questions
Is my data uploaded?
No. The conversion runs entirely in your browser.
Are comments preserved?
Comments are not part of the data model, so converting YAML to JSON drops them.
Is YAML safer to parse?
Parsing untrusted YAML can be risky in general, but here it is parsed locally and never executed.
