Format Details
XLSX
XLSX is the default spreadsheet format for Microsoft Excel since Office 2007, built on the Open XML standard and standardized by ISO. It stores worksheets, formulas, charts, pivot tables, and formatting in a compressed ZIP archive of XML files, making it more compact and corruption-resistant than the older XLS format. XLSX is supported by Google Sheets, LibreOffice Calc, Apple Numbers, and virtually every modern data tool.
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.
