Challenge: People enter data in various ways. If you ask 50 sales reps to record
a forecast for General Motors, you will fi nd that there are a dozen ways to spell
and/or abbreviate the name of that customer. Combine all the forecasts from
all the sales reps, and you will have the same customer spelled a multitude of
ways. Column A in Figure 126 shows some of the different ways to enter the
names of customers whose offi cial names are listed in column D.
Figure 126. When asked to type customer names, various employees will spell
or abbreviate them in various ways.
Setup: This is a classic problem known as the fuzzy match problem. The
problem was fi rst discussed at the MrExcel message board back in fall 2001,
with the fuzzy match challenge of the month. At that time, Juan Pablo Gonzalez
wrote in with a routine to determine the percentage match between two strings.
Damon Ostrander and others later followed up.
The question arose again at the message board in late 2003. Al_B_Cnu
adapted the code from the challenge to write complete FuzzyVLOOKUP ,
FuzzyHLOOKUP , and FuzzyPercent functions. I won’t reprint the 373 lines of
code here, but you can examine them in the sample fi le for this topic (download
from les.html).
Solution: The FuzzyPercent function compares text from two cells and
determines what percentage of the characters in the fi rst cell are in the same
sequence in the second cell. In Figure 127, cells A2 and B2 share 11 characters
in common. Because cell A2 contains 11 characters total, 73% of the characters
match cell B2, and the FuzzyPercent is 73%. Note that if you reverse A2
