About XLSX and XML
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
XLSX is the default spreadsheet format used by Microsoft Excel since 2007. It stores structured tabular data, formulas, charts, and pivot tables using XML inside a compressed archive. XLSX improves data integrity, reduces file size, and supports advanced analytics and automation. It is widely supported by spreadsheet software including Google Sheets and LibreOffice.
application/xml
Standard for providing a single, interchangeable master file format for distribution of content to various businesses.
Conversion Notes
Video conversion re-encodes both the video and audio streams to fit the target container and codec. Resolution, frame rate, and aspect ratio are preserved by default. If the source uses a codec not natively supported by XML, a compatibility codec is chosen automatically. Conversion time scales with file duration and resolution — 4K files may take several minutes to process.
