Input is processed only in the active browser tab's memory and is not sent to a ByteQuant server.
YAML ↔ JSON Converter
Converts YAML documents to JSON with a safe schema and valid JSON to readable YAML. Alias expansion and document size are bounded, and custom tags are not executed. Validate output against the target application's schema before using it as configuration.
Input and output are not stored. The optional usage counter keeps only tool identity and count, never content.
Output comes from disclosed rules or browser APIs and needs independent review before high-impact use.
A result in three steps
- 01
Paste YAML or JSON and choose the source format.
- 02
Run the local conversion and review parsing warnings.
- 03
Validate output against the target schema and application behavior.
When is this tool useful?
- ✓ Converting CI configuration
- ✓ Sharing API samples as YAML
- ✓ Surfacing indentation errors
Automated output is a preliminary assessment. Do not use it alone for legal, financial, medical, or security-critical decisions.
