# How To Use Excel XMATCH Function

Click to share! ⬇️

The XMATCH function in Excel is a powerful tool for finding a specific value within a range of cells. It is similar to the popular VLOOKUP function but with some important differences. Unlike VLOOKUP, which can only search for a value in the first column of a range and return a corresponding value from another column, XMATCH can search for a value anywhere within a range and return its position relative to the range. This makes it a more versatile option for certain data lookups and calculation types.

The XMATCH function also has the advantage of handling errors and missing data more gracefully than VLOOKUP. With VLOOKUP, a common problem is that if the value being searched for is not found, the function will return an error. However, with XMATCH, you can specify how the function should handle these cases by using the optional “match_type” parameter.

The XMATCH function is a valuable addition to your Excel toolbox, allowing you to perform more advanced data lookups and calculations with greater flexibility and robustness.

## Syntax and Parameters of the XMATCH Function

The syntax of the XMATCH function is as follows:

``XMATCH(lookup_value, lookup_array, match_type)``

where:

• `lookup_value` is the value that you want to find in the `lookup_array`. It can be a number, text, or a reference to a cell containing the value.
• `lookup_array` is the range of cells that contains the data you want to search. It can be a single row or column or a multidimensional range.
• `match_type` is an optional parameter that specifies the type of match to use. It can be a number between -1 and 1 or one of the following text values: “xlExact”, “xlApproximate”, and “xlNext”.
• 0 or “xlExact” specifies an exact match.
• -1 or “xlApproximate” specifies an approximate match.
• 1 or “xlNext” specifies a next smaller value match.

The XMATCH function returns the relative position of the `lookup_value` in the `lookup_array`, if it is found. If it is not found, it returns an error (NA) if match_type not set to -1.

It is important to note that the lookup_array must be sorted in ascending order for the match_type of 1 or “xlNext” to work properly.

You can also use the XMATCH function with other functions like INDEX and OFFSET for more powerful data lookups and calculations.

## How to Use the XMATCH Function in Different Match Types

The XMATCH function allows you to specify different types of match using the “match_type” parameter, which can be a number between -1 and 1 or one of the following text values: “xlExact”, “xlApproximate”, and “xlNext”.

• `Exact match`: This is the default match type if the “match_type” parameter is not specified or is set to 0 or “xlExact”. This match type looks for an exact match of the `lookup_value` in the `lookup_array`, and returns the relative position of the first matching cell. For example `=XMATCH(A1,B1:B100,0)` will return the position of A1 in range B1:B100 if it exists.
• `Approximate match`: To use an approximate match, set the “match_type” parameter to -1 or “xlApproximate”. With this match type, the function returns the relative position of the closest match to the `lookup_value` in the `lookup_array`, based on the value’s proximity to the values in the range. This is useful when looking up a value that may be slightly different from the actual data in the lookup range. For example `=XMATCH(A1,B1:B100,-1)` will return the approximate match of A1 in range B1:B100
• `Next Smaller match`: To use a next smaller value match, set the “match_type” parameter to 1 or “xlNext” . With this match type, the function looks for the closest value that is smaller than the `lookup_value` in the `lookup_array`, and returns the relative position of that cell. This is useful when looking up a value in a range of ordered data and you want to find the closest smaller value. For example `=XMATCH(A1,B1:B100,1)` will return the position of closest smaller value of A1 in range B1:B100.

## Examples of XMATCH Function in Real-World Scenarios

Here are a few examples of how the XMATCH function can be used in real-world scenarios:

1. Determining the ranking of a salesperson: Let’s say you have a spreadsheet with a list of salespeople and their sales figures for the month, and you want to determine the ranking of a specific salesperson. You can use the XMATCH function in combination with the INDEX function to return the ranking of the salesperson based on their sales figures. For example, the formula `=XMATCH(A1,B1:B100,0)` in cell C1 will return the ranking of the salesperson whose sales figures are in cell A1, where column B contains the sales figures of all salespersons and column C contains the ranking.
2. Finding a value in a large data set: Let’s say you have a spreadsheet with a large data set and you need to find a specific value within that data set. The XMATCH function can be used to quickly search through the data and return the relative position of the value. You can also use it with the INDEX function to return the value itself or additional information about the value.
3. Approximating a value: When you have a large data set and you want to find a value that is not exact in the data set, you can use the approximate match option of the XMATCH function. It will return the closest match possible. For example: `=XMATCH(A1,B1:B100,-1)` will return the approximate match of A1 in range B1:B100
4. Finding closest smaller value : When you have a large data set and you want to find the closest smaller value to a given value, you can use the next smaller match option of the XMATCH function. For example `=XMATCH(A1,B1:B100,1)` will return the position of closest smaller value of A1 in range B1:B100.

These are just a few examples of how the XMATCH function can be used, and the possibilities are almost endless depending on the specific needs of your data and calculations.

## Troubleshooting Common Errors with the XMATCH Function

Here are some common issues that can arise when using the XMATCH function, along with tips on how to troubleshoot them:

1. `#N/A` error: This error can occur if the XMATCH function is unable to find the `lookup_value` in the `lookup_array`, or if the `lookup_array` is not sorted properly for match_type of 1 or “xlNext”. To resolve this, check that the `lookup_value` is spelled correctly and exists in the `lookup_array`. Also ensure that the `lookup_array` is sorted in ascending order if match_type of 1 or “xlNext” is being used.
2. Incorrect results: This can happen if the `lookup_value` and `lookup_array` are not in the same format (e.g. one is text and the other is a number), or if there are duplicates of the `lookup_value` in the `lookup_array`. To resolve this, ensure that the `lookup_value` and `lookup_array` are in the same format and that there are no duplicate values in the `lookup_array`.
3. The function returns an error when the match is not found and match_type not set to -1: Since the XMATCH function returns an error (NA) when the match is not found, this can cause unexpected behavior. To avoid this, you can use the IFERROR function to return an alternative value if an error is returned. For example, `=IFERROR(XMATCH(A1,B1:B100,0),"Not found")` returns “Not found” when match is not found instead of an error.
4. Unexpected results using “xlNext” match type with unsorted data. If the data is not sorted, the XMATCH function will not be able to give a correct result for “xlNext” match type. Always make sure that your data is sorted in ascending order when using this match type

Follow these troubleshooting tips to quickly and easily resolve any issues that may arise when using the XMATCH function, and ensure that your data lookups and calculations are accurate and reliable.

## Advanced Tips and Tricks for Using the XMATCH Function

1. Combining XMATCH with INDEX: The XMATCH function can be used in combination with the INDEX function to return the actual value of a cell at a certain position in a range. For example, if you have a range of data in A1:A100 and you want to find the value at the 5th position, you can use the formula `=INDEX(A1:A100,XMATCH(5,A1:A100,0))`. This will return the value at the 5th position in the range A1:A100
2. Using XMATCH in combination with other functions: XMATCH can be used with other functions such as OFFSET, COUNTIF, SUMIF, and other lookup and reference functions to create more powerful data lookups and calculations.
3. Using XMATCH with dynamic ranges: The XMATCH function can also be used with dynamic ranges created by functions such as INDEX and OFFSET. This allows you to perform lookups on varying data sets, or on data sets that change in size. For example, use the formula =XMATCH(A1,OFFSET(B1,0,0,COUNTIF(B:B,”<>”),1),0) to search for A1 in a dynamic range that is based on the data in column B.
4. Using XMATCH for data validation: you can use the XMATCH function to check whether a value entered into a cell is part of a list of valid values. If the XMATCH function returns an error, the value is not valid.
5. Use match_type -1 to find approximate matches: The approximate match option of the XMATCH function can be useful in situations where the data is not always exact, such as measurements or estimates.
