Convert XLK to PDF

The XLK file extension stands for Microsoft Excel Backup File. It is a backup file created by Microsoft Excel to store a copy of an existing Excel file (such as XLSX or XLS) to safeguard against data loss or corruption. This feature, which dates back to earlier versions of Excel, allows users to recover their work in case the original file becomes unusable. While newer Excel versions rely more on autosaving and version history, the XLK backup remains a useful tool for data recovery and archival purposes.

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.
