Excel INDEX/MATCH tl;dr

I was playing with Excel recently and for the hundredth time got stumped by how to use the INDEX/MATCH combo. For the hundredth time in the past years, I open the same damn website and the same damn explanation which took awhile because my brain actually needed to work to understand what’s going on.

I didn’t want to understand. I just want it to work. Yes, brain is smol.

So here I’m just gonna drop how to use it. Below is table A.

nameletterscore
ackbarA?
obi-wanB?
han soloC?

I want to find the corresponding score to the letter.

Below is table B, which holds the mapping of letter to score:

letterscore
A90
B80
C70

tl;dr, the formula to put for each row in the “score” column to get the corresponding score to the letter in the row is:

INDEX(
  <the_table_of_mappings_at_B>, 
  MATCH(
    <the_cell_value_to_lookup_at_A>, 
    <the_column_range_to_lookup_at_B>,
    0),
  <index_of_column_from_table_of_mappings>
)

Hopefully I won’t mess it up again.
