Convert XLK to SLK

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.

An SLK file, standing for Symbolic Link File, is a specialized file type used primarily in spreadsheet applications to facilitate data exchange. Originally introduced by Microsoft for its Multiplan spreadsheet program in the 1980s, the SLK format was later adopted by other spreadsheet software due to its simplicity and efficiency. These files are composed of ASCII text and include symbolic references to cells, allowing for easy parsing and manipulation of spreadsheet data. The primary use of SLK files is to enable seamless data transfer between different spreadsheet programs, ensuring compatibility and preserving the integrity of the data during exchange.
