How it works
- 1
Paste your input
Drop your JSON or YAML into the left textarea. The right side updates as you type.

Catch errors inline
Invalid input shows a line and column with a clear message - no guessing where the comma is missing.
- 3
Copy or download
Use the buttons under the output, or click the swap arrow to convert the other direction without retyping.
Frequently asked
Does it preserve key order?
Yes. JSON object key order is preserved and used as-is in the YAML output.
What about anchors and aliases?
YAML anchors are flattened on conversion to JSON. JSON cannot represent anchors directly.
Are my files uploaded anywhere?
No. Conversion happens entirely in your browser - nothing is sent to any server.
