Frequently asked questions
Is my data sent to a server during conversion?+
No. Conversion runs entirely in your browser. Your data never leaves your device, so you can safely convert config files containing secrets, credentials, or internal settings.
Does YAML-to-JSON conversion preserve comments?+
No. JSON does not support comments, so YAML comments are dropped during conversion. This is a limitation of the JSON format, not the tool.
Are YAML anchors and aliases supported?+
Yes. The converter resolves YAML anchors and aliases, expanding them into their full values in the JSON output. This makes the output self-contained.
Can I convert multi-document YAML files?+
The tool converts a single YAML document at a time. If your file contains multiple documents separated by ---, split them and convert each one individually.
