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.
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.
