Convert XLM to XLT

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 XLT file extension stands for Microsoft Excel Spreadsheet Template. It is used in Microsoft Excel versions 97 through 2003 to create templates containing default formatting, layout, and formulas. These templates serve as a starting point for generating new spreadsheets with consistent design and structure. Although replaced by the XLTX format in Excel 2007 and later versions, XLT files are still supported for backward compatibility.
