Daniel’s Extreme Lookup Collection

Today’s author is Daniel Wiesenfeld, an Excel and Access Power User who is sharing his Extreme Lookup Collection with us so we can use the Excel User Defined Functions (UDFs) he created to enhance the lookup functionality. His web site daanalytics.com is currently under construction and should be available soon.

In the Visual Basic Editor, insert a Module and paste the following code:

' XVLOOKUP (& XHLOOKUP)
' Works just like a vlookup (and hlookup) except that the user refers to a lookup colum (or row)
' rather than a range, it is 0 based and the user can "look left" (or "look upward") by using a negative
' column (or row) index.
' There is also an optional argument to allow the user to offset the cell to be returned by any number
' of rows (or columns)
' I do not give users the option to choose between exact or approximate match - it is always exact
