For convenience and readability,quarter(C4:F4) anddata(C5:F16) arenamed ranges. With XLOOKUP With theXLOOKUP function, the solution is straightforward. In thedynamic array version of Excel,the 12 values in E5:E16spillinto the range H5:H16. With FILTER You might not think of using theFILTER functionto filter columns, but it works fine. For another example of using FILTER on horizontal data,see this page. In thedynamic array version of Excel, these results willspillinto the range H5:H16. InLegacy Excel, you will need to enter this formula as amulti-cell array formula....

For convenience and readability,project(B5:B16) anddata(C5:F16) arenamed ranges. It can also be solved with the FILTER function. With XLOOKUP With theXLOOKUP function, the solution is simple. In thedynamic array version of Excel, the 4 values in C11:F11spillinto the range I5:L5. Seethis pagefor more details and examples. In thedynamic array version of Excel, these results willspillinto the range I5:L5. To do this, simplynestthe formula above inside the other function. If the project in H5 is changed, the formula recalculates, and a new result is returned....

The tricky part of the formula is the row_num argument, which is set to zero. you’re able to use INDEX to retrieve individual values, or entire rows and columns. MATCH supports approximate and exact matching, andwildcards(* ?) These values can be numbers, cell references, ranges, arrays, and constants, in any combination. SUM can handle up to 255 individual arguments.

In addition, we also want to get the corresponding date. All data is in anExcel Tablecalleddata,in the range B5:C16. This information represents the low temperature in Fahrenheit (F) for the dates as shown. There are several ways to solve this problem, as explained below. XLOOKUP function A simple solution is to use theXLOOKUP functionwithBoolean logic. In this particular example, wecoulduse TRUE instead of 1. Thedouble negative(–) is a simple way to perform this conversion....

Like the newer XLOOKUP function, LOOKUP can look up values in either rows or columns. However, unlike XLOOKUP, LOOKUP can only perform an approximate match. The second argument,lookup_vector, is the range or array to search. The third argument, result_vector, is the range or array from which to return a result.Result_vectoris optional. Ifresult_vectorisnotprovided, LOOKUP returns thevalueof the match found inlookup_vector. The LOOKUP function has two forms: vector and array. Most of this article describes thevectorform, but the last example below explains thearrayform....

For a given file, we want to locate the position (row number) for the last revision. This array result is fed into the IF function as the logical test. the row number inside the named range “files” where “filename1” appears. Use INDEX with this row number to retrieve information related to the last revision (i.e. full file name, date, user, etc). SEARCH returns the position offind_textinsidewithin_textas a number. MAX ignores empty cells, the logical values TRUE and FALSE, and text values....

Explanation This formula uses the LOOKUP function to find and retrieve the last matching file name. Next, the array is used as the denominator with 1 as numerator. The result looks like this: which goes into LOOKUP as the lookup_vector. This is a tricky solution to challenge #2. The LOOKUP function operates in approximate match mode only, and automatically ignores error values. Finally, LOOKUP uses 7 like an index to retrieve the 7th file in the list of files....

Explanation The LOOKUP function assumes data is sorted, and always does an approximate match. Notice the array contains only two unique values: the divide by zero error (#DIV/0!) and the number 1. LOOKUP searches the array for the value 2, ignoring the error values. Not finding 2, it falls back to the last 1, at position 7 in the lookup vector. LOOKUP’s default behavior makes it useful for solving certain problems in Excel....

If so, we return the predicted tide level, using thenamed rangepred. Notice we do not provide a “value if false” for either IF. That means if either logical test is FALSE, the outer IF will return FALSE. For more information on nested IFs,see this article. This is what makes this an array formula we are processing many values at once. The other values have been replaced with FALSE. The array above is returned directly to theMIN function....

you could use INDEX to retrieve individual values, or entire rows and columns. MATCH supports approximate and exact matching, andwildcards(* ?) The MIN function ignores empty cells, the logical values TRUE and FALSE, and text values.

All data is in anExcel Tablein the range B5:D15 named “data”. This problem can be solved with theXLOOKUP functionor withINDEX and MATCHtogether withBoolean logic. Both options are explained below. XLOOKUP function The XLOOKUP function is a modern replacement for theVLOOKUP function. A key benefit of XLOOKUP is that it can handlearray operationsas thelookup_arrayorreturn_array. This means we can construct thelookup_arraywe need as part of the formula. It is simply a common convention when usingBoolean logicin lookup formulas....

Explanation This is a basic example of VLOOKUP in “exact match” mode. (Read why this is necessaryhere). If no match is found, VLOOKUP will return the #N/A error.

This is because when LOOKUP can’t find a match, it will match the next smallest value. In case of duplicates, this formula will return the last match.Explanation of logic is here. LOOKUP’s default behavior makes it useful for solving certain problems in Excel.
