I need to loop through an array, do an index match for tens of thousands of records and the call to worksheet.function is extremely slow. Any way to avoid the slowness or the call altogether?<br />

Excel VBA, Can you use Index, Match in VBA without calling Worksheet.Function?

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

VBScript (Visual Basic Scripting Edition) is an interpreted scripting language developed by Microsoft that is modeled on Visual Basic, but with some important differences. VBScript is commonly used for automating administrative and other tasks in Windows operating systems (by means of the Windows Script Host) and for server-side scripting in ASP web applications. It is also used for client-side scripting in Internet Explorer, specifically in intranet web applications.
