Turn a JSON response or config into clean, readable YAML — and back again — on your own device.
A .yaml or .json file — or paste below · converted on your device, nothing uploaded
No size limit · files are processed on your device and never uploaded · how it works
JSON in
YAML out
Converts between YAML and JSON with a full YAML 1.1 parser — anchors, multi-line strings and nested maps all handled. Runs in your browser.
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Take an API response or a JSON config and turn it into tidy, correctly indented YAML — the format CI pipelines, Kubernetes manifests and Docker Compose files use because it is easier to read and diff. Nested objects and arrays are laid out cleanly so the result is ready to commit.
The reverse — YAML to JSON — is one click, and it all runs in your browser, so nothing is uploaded. Need to validate the JSON first? Use the JSON Formatter.
YAML is easier to read and edit for config files (CI pipelines, Kubernetes, Docker Compose). This gives you tidy YAML from any JSON in one step.
Yes — flip the direction to parse YAML back into JSON, minified or pretty-printed.
No — everything runs in your browser.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
InfyTool is built by the same team as these free libraries.
