*The tutorial introduces the new Excel XMATCH function and shows how it is better than MATCH for solving a few common tasks.*

In Excel 365, the XMATCH function was added to supersede the MATCH function. But before you start upgrading your existing formulas, it would be wise to understand all advantages of the new function and how it differs from the old one.

In summary, the XMATCH function is same as MATCH but more flexible and robust. It can look up both in vertical and horizontal arrays, search first-to-last or last-to-first, find exact, approximate and partial matches, and use a faster binary search algorithm.

The XMATCH function in Excel returns the relative position of a value in an array or a range of cells.

It has the following syntax:

XMATCH(lookup_value, lookup_array, [match_mode], [search_mode])

Where:

**Lookup_value** (required) - the value to look for.

**Lookup_array** (required) - the array or range of cells where to search.

**Match_mode** (optional) - specifies which match type to use:

- 0 or omitted (default) - exact match
- -1 - exact match or the next smallest value
- 1 - exact match or the next largest value
- 2 - wildcard match (*, ?)

**Search_mode** (optional) - specifies the search direction and algorithm:

- 1 or omitted (default) - search from first to last.
- -1 - search in reverse order from last to first.
- 2 - binary search ascending. Requires
*lookup_array*to be sorted in ascending order. - -2 - binary search descending. Requires
*lookup_array*to be sorted in descending order.

Binary search is a faster algorithm that works efficiently on sorted arrays. For more info, please see Search mode.

The XMATCH function is only available in Excel for Microsoft 365 and Excel 2021. In Excel 2019, Excel 2016 and earlier versions, this function is not supported.

To get a general idea of what the function is capable of, let's build an XMATCH formula it its simplest form, defining only the first two required arguments and leaving the optional ones to their defaults.

Supposing, you have a list of oceans ranked by their size (C2:C6) and you wish to find the rank of a particular ocean. To have it done, simply use the ocean's name, say *Indian*, as the lookup value and the entire list of names as the lookup array:

`=XMATCH("Indian", C2:C6)`

To make the formula more flexible, input the ocean of interest in some cell, say F1:

`=XMATCH(F1, C2:C6)`

As the result, you get an XMATCH formula to look up in a **vertical array**. The output is the relative position of the lookup value in the array, which in our case corresponds to the ocean's rank:

A similar formula works perfectly for a **horizontal array** too. All you need to do is to adjust the *lookup_array* reference:

`=XMATCH(B5, B1:F1)`

To effectively use XMATCH in your worksheets and prevent unexpected results, please remember these 3 simple facts:

- If there are two or more occurrences of the lookup value in the lookup array, the position of the
**first match**is returned if the*search_mode*argument is set to 1 or omitted. With*search_mode*set to -1, the function searches in reverse order and returns the position of the**last match**as demonstrated in this example. - If the lookup value
**is not found**, a #N/A error occurs. - The XMATCH function is
**case-insensitive**by nature and cannot distinguish the letter case. To distinguish lowercase and uppercase characters, use this case-sensitive XMATCH formula.

The following examples will help you gain more understanding about the XMATCH function and its practical uses.

The matching behavior of XMATCH is controlled by the optional **match_mode** argument:

- 0 or omitted (default) - the formula only searches for exact match. If an exact match is not found, a #N/A error is returned.
- -1 - the formula searches for exact match first, and then for the next smaller item.
- 1 - the formula searches for exact match first, and then for the next larger item.

And now, let's see how different match modes affect the formula's result. Suppose you want to find out where a certain area, say 80,000,000 km^{2}, stands among all the oceans.

If you use 0 for *match_mode*, you'll get a #N/A error, because the formula cannot find a value exactly equal to the lookup value:

`=XMATCH(80000000, C2:C6, 0)`

If you use -1 for *match_mode*, the formula will return 3, because the closest match smaller than the lookup value is 70,560,000, and it is the 3^{rd} item in the lookup array:

`=XMATCH(80000000, C2:C6, -1)`

If you use 1 for *match_mode*, the formula will output 2, because the nearest match larger than the lookup value is 85,133,000, which is the 2^{nd} item in the lookup array:

`=XMATCH(80000000, C2:C6, -1)`

The image below shows all the results:

The XMATCH function has a special match mode for wildcards: the *match_mode* argument set to 2.

In the wildcard match mode, an XMATCH formula accepts the following wildcard characters:

- Question mark (?) to match any single character.
- Asterisk (*) to match any sequence of characters.

Please keep in mind that wildcards only work with text, not numbers.

For instance, to find the position of the first item that starts with "south", the formula is:

`=XMATCH("south*", B2:B6, 2)`

Or you can type your wildcard expression in some cell, say F1, and supply the cell reference for the *lookup_value* argument:

`=XMATCH(F1, B2:B6, 2)`

With most Excel functions, you'd use tilde (~) to treat the asterisk (~*) or question mark (~?) as literal characters, not wildcards. With XMATCH, tilde is not needed. If you don't define the wildcard match mode, XMATCH will assume that ? and * are regular characters.

For example, the below formula will search the range A2:A7 exactly for the asterisk character:

`=XMATCH("*", A2:A7)`

In case there are several occurrences of the lookup value in the lookup array, you may sometimes need to get the position of the **last occurrence**.

The direction of search is controlled be the 4^{th} argument of XMATCH named **search_mode**. To search in reverse order, i.e. from bottom to top in a vertical array and from right to left in a horizontal array, *search_mode* should be set to -1.

In this example, we will return the position of the last record for a specific lookup value (please see the screenshot below). For this, set up the arguments as follows:

*Lookup_value*- the target salesperson in H1*Lookup_array*- salesperson names in C2:C10*Match_mode*is 0 or omitted (exact match)*Search_mode*is -1 (last-to-first)

Putting the four arguments together, we get this formula:

`=XMATCH(H1, C2:C10, 0, -1)`

Which returns the number of the last sale made by Laura:

To compare two lists for matches, you can use the XMATCH function together with IF and ISNA:

IF( ISNA( XMATCH(*target_list*, *search_list*, 0)), "No match", "Match")

For example, to compare List 2 in B2:B10 against List 1 in A2:A10, the formula takes the following form:

`=IF(ISNA(XMATCH(B2:B10, A2:A9)), "", "Match in List 1")`

In this example, we identify only matches, therefore the *value_if_true* argument of the IF function is an empty string ("").

Enter the above formula in the topmost cell (C2 in our case), press Enter, and it will "spill" into the other cells automatically (it is called a spill range):

**How this formula works**

At the heart of the formula, the XMATCH function searches for a value from List 2 within List 1. If a value is found, its relative position is returned, otherwise a #N/A error. In our case, the result of XMATCH is the following array:

`{#N/A;#N/A;2;#N/A;4;#N/A;#N/A;8;#N/A}`

This array is "fed" to the ISNA function to be checked for #N/A errors. For each #N/A error, ISNA returns TRUE; for any other value - FALSE. As the result, it produces the following array of logical values, where TRUE's represent non-matches, and FALSE's represent matches:

`{TRUE;TRUE;FALSE;TRUE;FALSE;TRUE;TRUE;FALSE;TRUE}`

The above array goes to the logical test of the IF function. Depending on how you configured the last two arguments, the formula will output the corresponding text. In our case, it's an empty string ("") for non-matches (*value_if_true*) and "Match in List 1" for matches (*value_if_false*).

Note. This formula only works in Excel 365 and Excel 2021 that support dynamic arrays. If you are using Excel 2019, Excel 2016 or earlier version, please check out other solutions: How to compare two columns in Excel.

XMATCH can be used in combination with the INDEX function to retrieve a value from another column associated with the lookup value, just like the INDEX MATCH formula. The generic approach is as follows:

INDEX (*return*_*array*, XMATCH (*lookup_value*, *lookup_array*)

The logic is very straightforward and easy to follow:

The XMATCH function calculates the relative position of the lookup value in the lookup array and passes it to the *row_num* argument of INDEX. Based on the row number, the INDEX function returns a value from any column that you specify.

For example, to look up the area of the ocean in E1, you can use this formula:

`=INDEX(B2:B6, XMATCH(E1, A2:A6))`

To look up in columns and rows simultaneously, use INDEX together with two XMATCH functions. The first XMATCH will get the row number and the second one will retrieve the column number:

INDEX (*data*, XMATCH (*lookup_value*, *vertical*_*lookup_array*), XMATCH (*lookup value*, *horizontal*_*lookup_array*))

The formula is similar to INDEX MATCH MATCH except that you can omit the *match_mode* argument since it defaults to exact match.

For instance, to retrieve a sales number for a given item (G1) in a specific month (G2), the formula is:

`=INDEX(B2:D8, XMATCH(G1, A2:A8), XMATCH(G2, B1:D1))`

Where B2:D8 are data cells excluding row and column headers, A2:A8 is a list of items and B1:D1 are month names.

As already mentioned, the Excel XMATCH function is case-insensitive by design. To force it to distinguish text case, use XMATCH in combination with the EXACT function:

MATCH(TRUE, EXACT(*lookup_array*, *lookup_value*))

To search in **reverse order** from last to first:

MATCH(TRUE, EXACT(*lookup_array*, *lookup_value*), 0, -1)

The following example shows this generic formula in action. Supposing you have a list of case-sensitive product id's in B2:B11. You are looking to find the relative position of the item in E1. A case-sensitive formula in E2 is as simple as this:

`=XMATCH(TRUE, EXACT(B2:B11, E1))`

**How this formula works:**

The EXACT function compares the lookup value against each item in the lookup array. If the compared values are exactly equal, including the characters case, the function returns TRUE, FALSE otherwise. This array of logical values (where TRUE's represent exact matches) goes to the *lookup_array* argument of XMATCH. And because the lookup value is TRUE, the XMATCH function returns the position of the first found exact match or the last exact match, depending on how you configured the *search_mode* argument.

XMATCH was designed as a more powerful and versatile replacement for MATCH, and so these two functions have a lot in common. However, there are essential differences.

The MATCH function defaults to exact match or the next smallest item (*match_type* set to 1 or omitted).

The XMATCH function defaults to exact match (*match_mode* set to 0 or omitted).

When the *match_mode* / *match_type* argument is set to 1:

- MATCH searches for exact match or next smallest. Requires that the lookup array shall be sorted in ascending order.
- XMATCH searches for exact match or next largest. Does not require any sorting.

When the *match_mode* / *match_type* argument is set to -1:

- MATCH searches for exact match or next largest. Requires sorting the lookup array in descending order.
- XMATCH searches for exact match or next smallest. Does not require any sorting.

To find partial matches with XMATCH, you need to set the *match_mode* argument to 2.

The MATCH function does not have a special wildcard match mode option. In most cases, you'll configure it for exact match (*match_type *set to 0), which also works for wildcard searches.

Like the new XLOOKUP function, XMATCH has a special *search_mode* argument that allows you to define the **direction of search**:

- 1 or omitted (default) - search first-to-last.
- -1 - reverse search last-to-first.

And choose a **binary search algorithm**, which is very quick and efficient on **sorted data**.

- 2 - binary search on data sorted ascending.
- -2 - binary search on data sorted descending.

*Binary search*, also called *half-interval search *or *logarithmic search*, is a special algorithm that finds the position of a lookup value within an array by comparing it to the middle element of the array. A binary search is much faster than a regular search but works correctly only on sorted lists. On unsorted data, it can return wrong results that may look pretty normal at first sight.

The syntax of MATCH does not provide for the search mode argument at all.

Unlike its predecessor, the XMATCH function was designed for dynamic Excel and handles arrays natively, without you having to press Ctrl + Shift + Enter. This makes formulas much easier to build and edit, especially when using a few different functions together. Just compare the following solutions:

XMATCH is a new function and it is only available in Excel for Microsoft 365 and Excel 2021.

The MATCH function is available in any version of Excel 365 through Excel 2007.

That's how to use the XMATCH function in Excel. I thank you for reading and hope to see you on our blog next week!
