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.
XML
XML (eXtensible Markup Language) is a flexible, human-readable markup language defined by the W3C for structuring, storing, and transporting data across different systems. Unlike HTML, XML uses custom-defined tags chosen by the author to describe the semantic meaning of data, making it self-documenting and extensible. XML underpins numerous data formats, web services (SOAP), configuration standards, and document formats including SVG, DOCX, and RSS.
