The Essbase Spreadsheet Toolkit package contains a library of Visual Basic (VB) functions for use in Excel for Windows. The Excel version of VB is commonly referred to as Visual Basic for Applications, or VBA.
The Essbase Spreadsheet Toolkit is a separately sold option in the Essbase Multidimensional Analysis System.
From a VBA program in Excel, you can also call VB functions in the API libraries. To learn how to use the API within VBA, see the Oracle Essbase Spreadsheet Add-in User's Guide.
