Excel MATCH Function

November 30, 2019 - by mahmood

MATCH is an Excel function used to locate the position of a lookup value in a row, column, or table. MATCH supports approximate and exact matching, and wildcards (* ?) for partial matches. Often, the INDEX function is combined with MATCH to retrieve the value at the position returned by MATCH.

=MATCH(E2,B3:B11,0)

=MATCH("pq*",B3:B11,0)

=MATCH("peach",B3:B9,0)

Excel INDEX Function

November 30, 2019 - by mahmood

The Excel INDEX function returns the value at a given position in a range or array. You can use index to retrieve individual values or entire rows and columns. INDEX is often used with the MATCH function, where MATCH locates and feeds a position to INDEX.

=INDEX(A1:B5,2,2) // returns value in B2
=INDEX(A1:B5,3,1) // returns value in A3

Excel Array formula

November 30, 2019 - by mahmood

An array formula performs an operation on multiple values instead of a single value. The final result of an array formula can be either one item or an array of items, depending on how the formula is constructed. To work correctly, many array formulas need to be entered with control + shift + enter. When you enter a formula this way, you’ll see the formula wrapped in curly braces {} in the formula bar.

{=SUM(LEN(B2:B11))}
