What this tool does
YAML is often preferred for configuration files because it is easier to read and edit than JSON. This tool parses JSON in the page and rewrites it as YAML, so you can move settings, Kubernetes manifests or API responses into a YAML-based config without a command-line tool.
How to use it
- Paste or type JSON in the input box.
- Choose an indent width and whether to sort keys alphabetically.
- Copy the YAML output or download it as a .yaml file.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Is my JSON uploaded anywhere?
- No. The conversion runs in JavaScript in your browser tab, so your data is never sent to a server.
- What happens with invalid JSON?
- The tool reports a parse error instead of guessing, so you can fix the exact problem before converting.
- Are comments or key order preserved?
- JSON has no comments to preserve. Key order is kept as written unless you turn on alphabetical sorting.
