What is XLSM?
XLSM is a Microsoft Excel file format that supports macros, allowing users to create and run automated tasks within spreadsheets. It is primarily used when users need to employ complex calculations or repetitive actions that are facilitated through VBA (Visual Basic for Applications) scripting.
Macro Compatibility Issues
When converting older Excel files to XLSM, macros may not be compatible or may not function as intended due to differences in Excel versions or security settings.
Loss of Data or Formatting
During conversion, some data or formatting may be lost if the original file contains features that are not supported in the XLSM format.
Security Warning Prompts
Opening XLSM files often triggers security warnings about enabling macros, which can confuse users unfamiliar with macros, leading to hesitation or disruption of work.
File Size Increase
XLSM files can be larger in size compared to their XLS counterparts due to the inclusion of macros and additional data, potentially causing storage or loading issues.
