Which file type should you select to save a workbook with macros enabled?

To save a workbook that contains macros, selecting the Excel Macro-Enabled Workbook file type is necessary. This format, denoted by the extension .xlsm, is specifically designed to support and retain any macros included in your workbook. When macros are written and used within Excel, it's essential to save the file in a format that enables them to function properly; otherwise, all macro functionality will be lost, and users may encounter errors when trying to use or run those macros.

Other file types, such as the standard Excel Workbook (.xlsx), do not support macros and will strip any macro code upon saving, making them unsuitable for this purpose. Similarly, the Excel 97-2003 Workbook (.xls) format may offer basic compatibility but is outdated and also does not fully support modern macro features as effectively as the .xlsm format. Lastly, the Excel Template format (.xltx) is intended for creating templates and also does not accommodate macros, further solidifying .xlsm as the preferred choice for macro-enabled workbooks.
