What is the .XLM File Extension?


.XLM File Extension Description:

The original Excel macro language allows you to write macros in a special spreadsheet called the macro sheet saved with the XLM file extension. These macros kept them apart from the assigned worksheets that were actually saved with the file extension XLS. Files with the .xlm file extension are often being referred as the Excel 4 macros or XLM macros.

The XLM macro language is the first user-accessible programming environment in Microsoft Excel, the first language for the XLM file extension and is the basis of the C language API. It enables users to create custom commands and functions on special macro sheets that look like ordinary worksheets.

Files with the .xlm file extension uses all the normal worksheet functions such as the LOG and SUM functions as well as other things which can never be supplied and entered on a set ordinary worksheet such as workspace information functions like "get.cell" and "get.workbook" and command-equivalent functions which enable the automation of usual user operations like name, define and paste.

Files with the .xlm file extension can also contain functions pertaining to add-ins like Register, macro specific functions as Argument and Volatile, flow control operations such as Goto and Return, and event traps that are command equivalent like "on.entry" and "on.time".

The XLM language in Excel version 4 is mapped to the C API, the reason why all DLLs were able to have all worksheet functions called, along with information functions of macro sheets. Thus, commands were also able have event traps set up in the files with the .xlm file extension.

In addition to worksheet and macro sheet functions and commands, the C API provides functions and command enumerations that can be called only by using callbacks from within the files with the .xlm file extension and the DLL.

Since the introduction of the XLM macro language, the easiest way for users to customize Microsoft Excel is to use XLM file extension instead of the XLS. This is because XLM language is far more sophisticated and the graphical user interface is more appealing.
