The built-in Excel lookup functions, such as VLOOKUP, are amazing. Would love to figure out what I’m doing wrong.This post explores Excel’s lookup functions, approximate matches, fuzzy lookups, and exact matches. Great tip for those that can get it to work, though. Tired both Paste and Match Style and Paste and Match Destination Formatting without success. Cannot get this shortcut to work for some reason. Running Word for Mac 15.28 (Office 365) on Sierra 10.12.1.Room attendants can record the.Index-Match-Match: How to Index-Match Rows and Columns. This post discusses the details of these ideas, and demonstrates how to perform a fuzzy lookup in Excel 2010 and later.Learn how to merge data from multiple worksheets based on a matching key column in Excel without using VLOOKUP function. Both of these are quite different from an approximate match or a fuzzy lookup. However, the VLOOKUP function, similar to Excel’s other lookup functions such as HLOOKUP and MATCH, is built to perform an exact match or a range lookup. The VLOOKUP function alone has saved countless hours in my recurring use workbooks.
![]() In the first step, the match, Excel must find the matching value. I’ll call step one the match, and step two the return. That is the basic idea, but the application of lookup functions are numerous and the implementations can become quite sophisticated and powerful.For this post, I’d like to split the tasks that a lookup function performs into two steps. For example, we could ask Excel to find “ABC Company” in a list of customer names. ![]() Find a value (the match) and compute the result (the return).It is important to note that the lookup value, the text string “ABC Company” must be found in the lookup range. And that my friend is the basic idea of the VLOOKUP function. FALSE means we are not performing a range lookupThis function is entered in C8 in the screenshot below.As you can see, the ID AC100 was successfully returned to the formula cell C8. 2 is the column that has the value we wish to return It is a boolean argument, meaning you can pass it a value of TRUE or FALSE, or any other representation of TRUE or FALSE. The Truth about the VLOOKUP Fourth ArgumentThe fourth argument of the VLOOKUP function is officially named: range_lookup. If the value is not the same, the function will not match it, and you’ll get an error, as shown in the screenshot below.Now that we have covered the basics, it is time to explore the VLOOKUP’s fourth argument. This is called an exact match. No leading spaces, no trailing spaces, no extra abbreviations or characters. “ABC Company” would not match “ABC Company, Inc.”, “ABC Co”, or “ABC Company “. Android emulator running slow on macIn some cases and in some data sets, this idea would work. The description Approximate Match would tend to imply that the function would match “ABC Company” and “ABC Company, Inc.” since they are approximately the same name. Excel describes the TRUE value as “Approximate Match” and FALSE as “Exact Match.” A clearer description would have been something like TRUE “You are doing a range lookup” and FALSE “You are not doing a range lookup” but in any event, the descriptions are what they are.When you select TRUE (Approximate Match) you are not asking Excel to match values that are approximately the same as each other. For example, when trying to find the correct commission rate based on the sales value. This is why the lookup range must be sorted in ascending order for the function to return an accurate result when the fourth argument is TRUE.This idea can be confusing when thinking about text strings, but makes more sense when thinking about numbers. For example, in the screenshot below, the function did not find a match between “ABC Company” and “ABC Company, Inc.” as evidenced by the incorrect ID returned in C8:In the following screenshot however, the function did find a match between “ABC Company” and “ABC Co” as evidenced by the expected ID returned to C8:The way that the function actually works when TRUE is selected is this: it walks down the list row by row, and ultimately stops on the row that is less than the value and where the next row is greater than the value. This is pretty easy to understand when thinking about numbers, but can be harder to visualize when thinking about text strings. It stops on the row that is less than the value, and where the next row is greater than the lookup value. It continues down until it finds a row that is greater than the lookup value, and then it stops on the previous row. This is illustrated in the screenshot below.The function walks down row by row trying to determine which row to stop on. You want to look up a value from within a range. But that they are likely a match, there is a probability that they are a match. ” We think about an approximate match as kind of fuzzy, where some of the characters match but not all.The idea of a fuzzy lookup is that the values are not a clear match, they are not identical. For example, “ABC Company” should match “ABC Company, Inc.,” “ABC Co,” and “ABC Company. What is a Fuzzy Lookup aka Approximate MatchAn approximate match, to us, means that two text strings that are about the same, but not necessarily identical, should match. This is why “ABC Company” will match “ABC Co”, because “ABC Co” is less than “ABC Company.” As you can see, this is not what we have in mind when thinking about approximate match. This is why “ABC Company” does not match “ABC Company, Inc.”, because “ABC Company Inc.” is greater than ABC Company. It does not change the behavior of any of the built-in lookup functions. It is called “Fuzzy Lookup Add-In for Excel” and is available at the time of this post at the link below:Once installed, this add-in performs fuzzy lookups. Microsoft has offered a way to work around this limitation by offering a free add-in.Microsoft offers a free add-in that enables Excel to perform fuzzy lookups. Since the built-in lookup functions do not perform fuzzy logic when performing the match, we hit a built-in limitation of Excel. ![]() Martch Column In Excel License Terms InYou can actually add a new custom configuration. The default Column Configuration options are Default, PhoneNumber, SSN, and ZipCode. Pretty heavy mathematics in there. Thanks Microsoft Research for this add-in!!I believe the add-in allows you to provide a “Transformation Threshold” for individual columns via the Column Configuration options. It also comes with a license, so, you’ll want to be sure to read the license terms in the LicenseTerms.rtf document included with the download.There is some extremely interesting computer science and math working behind the scenes, including Jaccard similarity, tokenization of records, and transformations. The add-in comes with instructions, a sample Excel file, and a pdf file with background and the logic it uses to do its magic. It basically generates a static report based on the settings you select.Here is a screenshot of the output, showing that it successfully matched “ABC Company” and “ABC Company, Inc.” in the same data set that caused our VLOOKUP function to fail.For more information about the fuzzy lookup add-in, and more detail on how to use it, please visit the Microsoft link above.
