At the core, this is just an INDEX / MATCH formula. The problem in this case is that we need to "screen out" the extraneous entries in the table so we are left only with entries that correspond to the animal we are looking up. This is done with the IF function here:
This snippet tests the values in B5:B10 to see if they match the value in G6 (the animal). Where there is a match, the corresponding values in C5:C11 are returned. If there is no match FALSE is returned. When G6 contains "cat", the resulting array looks like this:
This array is delivered directly to the MATCH function as the lookup_array. The lookup value for match comes from G7, which contains the weight (9 lbs in the example).
Note that match is configured for approximate match by setting match_type to 1, and this requires that the values in C5:C11 must be sorted.
MATCH returns the position of the weight in the array, and this is passed to the INDEX function as the row number. The lookup_array for INDEX are the sizes in D5:D10, so INDEX returns a size corresponding to the position generated by MATCH (the number 4 in the example shown).
The Excel INDEX function returns the value at a given location in a range or array. You can use INDEX to retrieve individual values, or entire rows and columns. The MATCH function is often used together with INDEX to provide row and column...
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, MATCH is combined...
The IF function runs a logical test and returns one value for a TRUE result, and another for a FALSE result. For example, to "pass" scores above 70: =IF(A1>70,"Pass","Fail"). More than one condition can be tested by nesting IF functions. The IF...
