Frequently Asked Questions

Does it preserve comments during YAML-to-JSON conversion?

No — YAML comments are not supported in the JSON standard and are stripped during conversion. If comments are critical, keep a copy of the original YAML.

Are YAML anchors and aliases supported?

The converter resolves YAML anchors (&) and aliases (*) into their expanded values in the JSON output, since JSON has no equivalent concept.
