The yaml to json works like this: it converts YAML to JSON and JSON back to YAML with 2-space output and quote-normalization. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.
How to use the YAML to JSON
Paste the input (code, data or query).
Run the operation - formatting and validation are instant.
Read any validation message before trusting the output.
Copy the result into your project.
Features

Copying output without checking escaping

All parsing and transformation happens locally in this tab - your code and data are not sent anywhere.
Frequently asked questions
Why did my YAML comments disappear?
JSON has no comment syntax, so anything converted through JSON loses them - convert copies, not masters.
What happens to YAML anchors and aliases?
They are resolved into plain duplicated structures during conversion, so the JSON output is standard and any parser can read it.
When is YAML preferred over JSON?
Configuration files - YAML's comments and cleaner lists make hand-edited configs readable, while JSON remains the wire format. This converter bridges the two exactly.
