Format Details
XLS
XLS is the legacy binary spreadsheet format used by Microsoft Excel from 1987 through the Office 2003 era, based on Microsoft's proprietary Binary Interchange File Format (BIFF). It stores worksheets, formulas, charts, and macros in a binary structure that requires Microsoft's format specification to parse correctly. XLS remains common in older enterprise systems and when compatibility with legacy versions of Excel is required.
PDF (Portable Document Format) was created by Adobe in 1992 and has become the worldwide standard for sharing documents with precisely fixed layouts. It preserves fonts, images, vector graphics, and formatting identically across every operating system, device, and printer. PDF supports digital signatures, encryption, interactive forms, and embedded multimedia, making it essential for official documents, contracts, reports, and professional publications.
