Which extracts data where color is "RED", respecting upper and lower case.
This formula relies on the FILTER function to retrieve data based on a logical test. The arrayargument is provided as B5:D15, which contains all of the data without headers. The include argument is an expression based on the EXACT function:
The EXACT function compares two text strings in a case-sensitive manner. If the two strings are exactly the same, EXACT returns TRUE. If the two strings are not exactly the same, EXACT returns FALSE. Since we are giving EXACT a range with 11 values as the first argument, and the string "RED" as the second, EXACT returns an array with 11 results like this:
Notice the position of TRUE values in this array corresponds to the rows where the color is "RED".
This array returned directly to the FILTER function as the include argument. FILTER uses the array to filter the range B5:D15, and returns the three rows where the color is "RED". Rows where the color is "Red" are not included.
The SEARCH function returns the position of the search string when found, and the #VALUE! error if not found. We use this fact to test whether the search string is found by using the ISNUMBER function to "catch" valid numeric positions. ISNUMBER...
This formula relies on the FILTER function to retrieve data based on a logical test. The array argument is provided as B5:D14, which contains the full set of data without headers. The include argument is based on a logical test based on the ISNUMBER...
In this example, the goal is to perform a case-sensitive lookup on the color in the "Color" column. In other words, a lookup value of "RED" must return a different result from a lookup value of "Red". By default, Excel is not case-sensitive and this...
The Excel SEARCH function returns the location of one text string inside another. SEARCH returns the position of the first character of find_text inside within_text. Unlike FIND, SEARCH allows wildcards, and is not case-sensitive.
The Excel ISNUMBER function returns TRUE when a cell contains a number, and FALSE if not. You can use ISNUMBER to check that a cell contains a numeric value, or that the result of another function is a number.
