Frequently asked questions
Do data converters validate input?
Yes. Data tools surface parsing errors and warnings instead of silently changing malformed input. Invalid JSON, YAML, or CSV produces a clear error message.
Are conversions lossless?
Conversions between text-based formats (CSV, JSON, YAML, XML) are lossless for well-formed input. Type coercion notes are shown where values are automatically interpreted.
