XLM File – What is .xlm file and how to open it?

Definition and Usage of XLM Files

An XLM file, short for Microsoft Excel Macro, is a type of scripting file used for automating tasks and extending the functionality of Microsoft Excel. It employs the XLM Macro Language (XLM), a macro programming environment embedded within Excel, to provide a customizable platform for tailoring the spreadsheet software according to the user’s specific needs.

XLM files contain a collection of macros written in the XLM scripting language. These macros are essentially a series of commands that automate repetitive or complex tasks, allowing users to increase their productivity and streamline their workflows. Common use cases for XLM macros include performing calculations, formatting data, creating charts, and managing workbooks. By leveraging the power of macros, users can save time, reduce errors, and enhance their overall efficiency in using Excel.

Opening an XLM File in Microsoft Excel

XLM files are Microsoft Excel Macro files created in older versions of Excel and contain macros written in the Excel Macro Language (XLM). To open an XLM file in modern versions of Microsoft Excel, follow these steps:

1. Enable Legacy Mode: In Excel, go to the “File” menu, select “Options,” and navigate to the “Trust Center” settings. Click on “Trust Center Settings,” and under “Macro Settings,” select “Disable all macros without notification.”
2. Open the XLM File: Browse to the location of the XLM file on your computer and click “Open.”
3. Convert the XLM File: Excel will display a security warning indicating that the file contains macros. Click on “Enable Content,” and Excel will convert the XLM file into a modern Excel Workbook file (.XLS or .XLSX) format.
4. Trust the File: Once converted, Excel will ask you to trust the converted workbook. Click on “Trust this Workbook” to enable the macros in the file.

Opening an XLM File in Notepad

If you do not have access to Microsoft Excel, you can also open an XLM file in Notepad or another text editor. This will allow you to view the contents of the file, including the XLM macros.

1. Open Notepad: Open Notepad on your computer.
2. Open the XLM File: Drag and drop the XLM file into Notepad.
3. View the Contents: The XLM macros will be displayed in the Notepad window. However, you will not be able to edit or execute the macros in Notepad.

History and Purpose of XLM Files

XLM (Microsoft Excel Macro) files are a type of legacy file format that was used in early versions of Microsoft Excel. They contain macros, which are automated sets of instructions that can be used to perform repetitive tasks within Excel. XLM files were introduced in Excel 4.0, released in 1992, and were primarily used before the introduction of the Visual Basic for Applications (VBA) programming language in Excel 5.0. VBA gradually replaced XLM as the preferred macro programming language in Excel, and XLM files are now rarely used.

Technical Details of XLM Files

XLM files are text-based files that consist of a series of commands and statements in the XLM macro language. These commands and statements allow users to perform various tasks within Excel, such as manipulating data, formatting cells, and creating charts. XLM files can also contain custom functions and user-defined data types. The XLM macro language is similar to other macro languages, but it has specific syntax and commands that are unique to Excel. XLM files are typically stored with the .xlm file extension and can be opened and edited using any text editor or dedicated XLM editor.
