JSON to YAML

12 tools

Convert JSON to YAML and back.

100% client-side — nothing you process is ever uploaded

Everything you'd need a dedicated JSON app for — formatting, a collapsible tree view, structural diffing, converting to/from CSV, YAML, and XML, generating TypeScript interfaces and JSON Schemas, querying with JSONPath, and validating JSON Lines — runs entirely client-side using your browser's native JSON engine, so nothing you paste is ever sent to a server.

Frequently asked questions

Why convert between JSON and YAML?

Many config formats (Docker Compose, Kubernetes, GitHub Actions, CI pipelines) use YAML, so this helps when moving data between JSON APIs and YAML config files.

Does it support anchors and multi-document YAML?

It covers common cases (objects, arrays, strings, numbers, booleans, null); advanced YAML features like anchors/aliases are parsed but not specially preserved on the way back to JSON.

Is my data sent to a server?

No, conversion runs entirely in your browser.
