Chapter 8: Using Lookup Functions 229
Figure 8-14: The formula in cell B2 returns the address in the Data range for the value in cell B1.
If the Data range occupies a single row, use this formula to return the address of the Target value:
=ADDRESS(ROW(Data),COLUMN(Data)+MATCH(Target,Data,0)-1)
If the Data range contains more than one instance of the Target value, the address of the first
occurrence is returned. If the Target value is not found in the Data range, the formula returns
#N/A.
Looking up a value by using the closest match
The VLOOKUP and HLOOKUP functions are useful in the following situations:
You need to identify an exact match for a target value. Use FALSE as the function’s
fourth argument.
You need to locate an approximate match. If the function’s fourth argument is TRUE or
omitted and an exact match is not found, the next largest value that is less than the
lookup value is used.
But what if you need to look up a value based on the closest match? Neither VLOOKUP nor
HLOOKUP can do the job.
Figure 8-15 shows a worksheet with student names in column A and data values in column B. Range
B2:B20 is named Data. Cell E2, named Target, contains a value to search for in the Data range. Cell
E3, named ColOffset, contains a value that represents the column offset from the Data range.
