Fidelity When Converting ODS to HTM

Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. OpenDocument Spreadsheet preserves the full range. HTML Document maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the HTML Document format supports it. Format-exclusive metadata fields that have no equivalent in HTML Document are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality OpenDocument Spreadsheet input produces an excellent HTML Document output. Since the target format is lossless, output quality matches your input exactly.

Document conversion from OpenDocument Spreadsheet to HTML Document involves translating formatting, layout, fonts, and embedded content between document models. Complex formatting like tables, headers, footers, and page breaks are mapped as accurately as possible. Some format-specific features (macros, track changes, advanced styles) may not have direct equivalents in the target format.
