Excel-xlookup

Use the XLOOKUP function to find things in a table or range by row. For example, look up the price of an automotive part by the part number, or find an employee name based on their employee ID. With XLOOKUP, you can look in one column for a search term and return a result from the same row in another column, regardless of which side the return column is on.

Note: XLOOKUP is not available in Excel 2016 and Excel 2019, however, you may come across a situation of using a workbook in Excel 2016 or Excel 2019 with the XLOOKUP function in it created by someone else using a newer version of Excel. 

Syntax

The XLOOKUP function searches a range or an array, and then returns the item corresponding to the first match it finds. If no match exists, then XLOOKUP can return the closest (approximate) match. 

=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode]) 

Argument	Description
lookup_value Required*	The value to search for *If omitted, XLOOKUP returns blank cells it finds in lookup_array.
lookup_array Required	The array or range to search
return_array Required	The array or range to return
[if_not_found] Optional	Where a valid match is not found, return the [if_not_found] text you supply. If a valid match is not found, and [if_not_found] is missing, #N/A is returned.

[match_mode] Optional

Specify the match type: 0 - Exact match. If none found, return #N/A. This is the default. -1 - Exact match. If none found, return the next smaller item. 1 - Exact match. If none found, return the next larger item. 2 - A wildcard match where *, ?, and ~ have special meaning.

[search_mode] Optional

Specify the search mode to use: 1 - Perform a search starting at the first item. This is the default. -1 - Perform a reverse search starting at the last item. 2 - Perform a binary search that relies on lookup_array being sorted in ascending order. If not sorted, invalid results will be returned. -2 - Perform a binary search that relies on lookup_array being sorted in descending order. If not sorted, invalid results will be returned.

Examples

Example 1    uses XLOOKUP to look up a country name in a range, and then return its telephone country code. It includes the lookup_value (cell F2), lookup_array (range B2:B11), and return_array (range D2:D11) arguments. It doesn't include the match_mode argument, as XLOOKUP produces an exact match by default.

Note: XLOOKUP uses a lookup array and a return array, whereas VLOOKUP uses a single table array followed by a column index number. The equivalent VLOOKUP formula in this case would be: =VLOOKUP(F2,B2:D11,3,FALSE)

Example 2    looks up employee information based on an employee ID number. Unlike VLOOKUP, XLOOKUP can return an array with multiple items, so a single formula can return both employee name and department from cells C5:D14.

———————————————————————————
Example 3    adds an if_not_found argument to the preceding example.

Example 4    looks in column C for the personal income entered in cell E2, and finds a matching tax rate in column B. It sets the if_not_found argument to return 0 (zero) if nothing is found. The match_mode argument is set to 1, which means the function will look for an exact match, and if it can't find one, it returns the next larger item. Finally, the search_mode argument is set to 1, which means the function will search from the first item to the last.

Note: XARRAY's lookup_array column is to the right of the return_array column, whereas VLOOKUP can only look from left-to-right.

Example 5    uses a nested XLOOKUP function to perform both a vertical and horizontal match. It first looks for Gross Profit in column B, then looks for Qtr1 in the top row of the table (range C5:F5), and finally returns the value at the intersection of the two. This is similar to using the INDEX and MATCH functions together.

Tip: You can also use XLOOKUP to replace the HLOOKUP function.

Note: The formula in cells D3:F3 is: =XLOOKUP(D2,$B6:$B17,XLOOKUP($C3,$C5:$G5,$C6:$G17)).

———————————————————————————

Example 6    uses the SUM function, and two nested XLOOKUP functions, to sum all the values between two ranges. In this case, we want to sum the values for grapes, bananas, and include pears, which are between the two.

The formula in cell E3 is: =SUM(XLOOKUP(B3,B6:B10,E6:E10):XLOOKUP(C3,B6:B10,E6:E10))

How does it work? XLOOKUP returns a range, so when it calculates, the formula ends up looking like this: =SUM($E$7:$E$9). You can see how this works on your own by selecting a cell with an XLOOKUP formula similar to this one, then select Formulas > Formula Auditing > Evaluate Formula, and then select Evaluate to step through the calculation. 

Note: Thanks to Microsoft Excel MVP, Bill Jelen, for suggesting this example.
