Personal.xlsb file in XLSTART directory

The Personal.xlsb file in Windows is a hidden Excel workbook that opens automatically whenever you start Microsoft Excel. This file is typically used to store macros, custom functions, and VBA (Visual Basic for Applications) code that you want to be available whenever Excel is running. VBA code contained within the file may lead to crashes or unexpected errors in Slice. It’s crucial to either scrutinize the script within the file or remove it from the XLSTART directory to prevent these issues.

Personal.xlsb can be found in %AppData%\Microsoft\Excel\XLSTART
