Technical Quality Assessment
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. Excel 97-2003 preserves the full range. ASS Subtitle maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the ASS Subtitle format supports it. Format-exclusive metadata fields that have no equivalent in ASS Subtitle are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality Excel 97-2003 input produces an excellent ASS Subtitle output. Since the target format is lossless, output quality matches your input exactly.
