| Description | XLSM is an advanced version of XLS format, a Macro-enabled MS Excel file. Just like XML files, XLSM files use a combination of XML and ZIP compression algorithms, which reduce file size significantly and thus facilitate storage and sharing. Unlike its predecessor, the XLSM format features a macro – a Visual Basic programming code. Therefore, every time you try to open an XLSM file, there will be a warning about a potential threat. Please, do not open XLSM files received via email from unfamiliar sources. These files are compatible with Windows 7/8/Vista/XP. |
