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 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.
