YAML to JSON
100% Client-SideYAML to JSON helps you convert supported YAML structures into JSON for APIs, tooling or debugging. It is meant for quick development work such as moving configuration into JSON, checking parsed YAML structure, and feeding YAML-derived data into JSON-only systems.
YAML supports features that don't map cleanly to JSON, such as anchors, custom tags and some scalar types. Comments, anchor names and presentation style are always lost. Review the converted output.

In-Browser vs. Server-Based Tools

|---|---|---|
| Privacy | Files stay on your device and are never transmitted. | Files are uploaded to and processed on a third-party server. |
| Speed | No upload or download wait; speed depends on your device. | Upload and download time grows with file size and connection speed. |
| File size limits | No imposed limit; bounded by your device's memory. | Commonly capped per file or per task, with higher limits on paid plans. |
| Account required | No signup or login. | Often required for larger files or repeated use. |
| Data retention | Nothing to retain; data is cleared from memory. | Files may be stored for a period before deletion. |
