Convert XLM to DIF

The XLM file extension stands for "Excel Macro", a format used in early versions of Microsoft Excel to store macro instructions. Introduced with Excel 4.0 in the early 1990s, XLM files enabled automation of repetitive tasks by recording sequences of actions performed within the spreadsheet. They were pivotal in the evolution of Excel's macro capabilities, which later transitioned to VBA (Visual Basic for Applications). While XLM is largely obsolete now, understanding its role is crucial for grasping the history of Excel's automation features.

The Data Interchange Format (DIF) file extension is a standardized format used primarily for importing and exporting spreadsheet data between different software applications. Originating in the 1980s, DIF was developed by Software Arts for their pioneering spreadsheet program, VisiCalc. Despite its age, DIF remains relevant due to its simplicity and ease of implementation, facilitating interoperability among various data processing tools. Its structured, plain text nature makes it particularly suitable for transferring tabular data while maintaining data integrity across different platforms.
