The XLSM file extension is an open XML macro-enabled Microsoft Excel spreadsheet, created with Microsoft Office. This type of spreadsheet allows combining data grids with other features such as graphical elements and also offers the possibility to use macros that serve to extend the functionality of the Excel.
Technical Specification
The encoding of the XLSM file extension is based on a Markup Language (XML) that converts this type of document into a series of marked elements. These elements store all kinds of information associated with the spreadsheet, including text, numerical values, formulae, formatting details and data in a row or column format. Although this type of file does not support as many features as the XLSX files, it offers the possibility to include multiple macros that can automate certain actions.
Similar File Extensions
Other types of spreadsheets that have similar functionality to the XLSM Documents are:
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .XLSM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .XLSM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .XLSM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .XLSM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .XLSM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .XLSM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .XLSM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .XLSM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .XLSM file) will be extended to the maximum.
It is also good to check
- if the .XLSM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
