Paste YAML into the left box and click the button - the tool auto-detects YAML, JSON, or CSV input and always converts to JSON here, so you never have to pick a format manually.
There is no file picker and no download step - the result lands in the read-only box on the right and the Copy Output button puts it on your clipboard, ready to paste into your own file or editor.
YAML to JSON Converter
Paste YAML text on the left and click the button to get pretty-printed JSON on the right. The tool detects the format automatically, so pasting JSON or CSV back in converts it just as easily.
Key features
- In-browser text editor - paste your input directly into the box.
- Parses and serializes the input in the browser, then pretty-prints the JSON output.
- Copies the formatted result to the clipboard in one click.
- If a line cannot be parsed as JSON, CSV, or YAML, the output box shows the parser error instead of failing silently.
When to use it
Typical use: reading a Kubernetes manifest, a CI config, or any YAML config file as plain JSON so a script or API that only understands JSON can consume it.
Your data stays private
Everything runs locally in this browser tab; your data is never uploaded to a server.
