FAQ
Are YAML comments or formatting preserved?
Conversions focus on data structure, so comments and certain formatting details may not be preserved.
Can it handle large JSON/YAML?
Yes within browser memory limits. Very large inputs can be slow.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded.
