Convert XLS (Excel) to PDF

The XLS file extension, short for "Excel Spreadsheet", is a legacy format used by Microsoft Excel for storing spreadsheet data. Introduced with Excel 2.0 in 1987, it was the primary format until the introduction of XLSX in 2007. XLS files contain data organized in rows and columns, supporting formulas, macros, and various formatting options, making them essential for data analysis and financial reporting. Despite being replaced by the more robust and secure XLSX format, XLS files remain widely used in many legacy systems and applications.

The Portable Document Format (PDF) is a file extension created by Adobe Systems in 1993 to facilitate document exchange across different systems. PDFs preserve the formatting of source documents, making them ideal for sharing text, images, and graphics in a consistent manner. Commonly used for forms, manuals, e-books, and reports, PDF files are platform-independent, ensuring the content appears the same on various devices and operating systems. This versatility has solidified its status as a standard in digital documentation, enhancing both compatibility and security in file sharing.
