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. When implemented in the right way for special projects or in recurring use workbooks, they are able to save a ton of time. The built-in Excel lookup functions, such as VLOOKUP, are amazing. On the Home tab, in the Styles grouping, under the Conditional Formatting drop down choose Highlight Cells.This post explores Excel’s lookup functions, approximate matches, fuzzy lookups, and exact matches.To simplify this post, we’ll use just one as the example. Text to Columns in Excel is a method which is used to separate a text in different columns based on some delimited or any fixed width, there are two options to use text to columns in excel one is by using a delimiter where we provide delimiter as an input such as comma space or hyphen or we can use fixed defined width to separate a text in the adjacent columns.The built-in Excel lookup functions, such as VLOOKUP, HLOOKUP, and MATCH, work with similar lookup logic. Select multiple adjacent rows or columns: Click the.Excel Text to Columns.For example, we could ask Excel to find “ABC Company” in a list of customer names. To do that, select the first column and as you select (24) The basic idea of an Excel lookup function is to look for a value in a list. •0 votes: Yes, it is possible to select the first and last column and then have the middle columns be selected.Some lookup functions, such as the MATCH function, tell Excel to return the position number. That is, what value the function should return to the cell. You are asking Excel to find the lookup value in the lookup range.Step two, the return, is the function’s result. You tell Excel the value to find, such as “ABC Company” and you tell Excel where to look, such as in a range of cells. In the first step, the match, Excel must find the matching value. I’ll call step one the match, and step two the return.
![]() 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 Assuming the customer name was entered in C7, and the customers were stored in a Table named Table1, then the following function would do the trick: So far so good?I would like to find a specific customer name “ABC Company” in a list of customers, and if found, I would like Excel to return the customer id which is found in the next column.I would use a VLOOKUP function, and I would ask it to find “ABC Company” in the Customer Table, and return the ID. So, based on which lookup function you select, and which function argument values you enter, Excel knows what to return once it finds its match. ![]() 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. The thing that tends to mislead Excel users is the description that Microsoft used for these options. 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. Access the integrated nuget support visual studio for macThis 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. But this idea does not work in all cases, and thus, can’t be relied upon in our workbooks. 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. In this case, you want to perform a range lookup. 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. The key to understanding this function argument however, is to realize that the logic is identical when operating on text strings and numbers. This is pretty easy to understand when thinking about numbers, but can be harder to visualize when thinking about text strings. Since the built-in lookup functions do not perform fuzzy logic when performing the match, we hit a built-in limitation of Excel. They likely represent the same underlying entity.Now that we realize the VLOOKUP function does not truly perform approximate match logic, at least, not in the way we want it, what do we do? Add-InWhen you hit a wall, go around it. 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. Basically, you define step one the match. It is an add-in which basically processes two lists and computes the probability of a match.You specify the two tables, and within each table the columns to inspect. It does not enable your VLOOKUP functions to perform fuzzy lookups. 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. Identify Differences In Columns In Excel How To Use ItIt 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. You hit go, and the add-in performs its work, and then outputs the resulting table starting at the active cell. You can also specify the probability threshold. On the bottom of the Add-In panel, you’ll see a Configure… button which opens the Configure dialog. You 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.
