Registry File maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the Registry File format supports it. Format-exclusive metadata fields that have no equivalent in Registry File are gracefully omitted without affecting the converted content.

Extracting structured data from Keynote Presentation documents to Registry File data format involves parsing the document content and organizing it into a structured representation. Tabular data, lists, and key-value pairs are identified and converted. This is useful for data migration, analysis, and programmatic processing of document content.
