Frequently asked questions

Are conversions completely lossless?

Not always. Comments, YAML anchors and tags, TOML date distinctions, XML attributes, ordering, and INI arrays do not map perfectly across every data model. The editor reports common loss risks.

Are configuration files uploaded?

No. Parsing, conversion, tree inspection, comparison, and export run in this browser.

Does XML conversion validate an XSD?

No. It checks well-formed XML and converts elements, attributes, and text into a predictable object model; it does not perform XSD, DTD, or application-specific validation.

Can I validate converted JSON with a schema?

Yes. Export or copy the JSON into the related JSON Schema Validator & Mock Data Generator for Draft 7, 2019-09, or 2020-12 validation.
