如果在另一列上找到一个单元格的值，如何从与同步单元格在同一行的另一列返回该单元格的值？

Question

My Excel table is looking like this.

A column is the one that I want to fill in with correct data. 
B column is where the lookup values are.
C column is the one where I want to extract data from. 
D column is where data from B column will be searched.

For example, if data from B2 is found on D7 cell, I want to have in A2 the value from C7.

It would be much appreciated your help because I would like to learn as much as I can about excel formulas.

Answer 1

In A1 enter:

=INDEX(C$1:C$15,MATCH(B1,D$1:D$15,0))

and copy down:

Note:

MATCH() finds the row.
INDEX() grabs the value.

Answer 2

Chris is right, looks like you need a vlookup, example

B1 would be

=Vlookup(A1,c1:d200,2,0)

B2 would be

=Vlookup(A2,c1:d200,2,0)

And so on

It works like this Vlookup (value to lookup, range the lookup and return values are in, column number from range you want to return, exact match only (0 or false))

Though Chris's link is more detailed
