I have a sheet with two columns and some data, and another sheet with a column and the same data of the first column in the first sheet, but in a different position. So, i need to insert in the column 2 of the second sheet the correct data.
How can i do it?

Example:

_Sheet 1:

Column1 Column2
A 1
B 2
C 3

_Sheet 2:

Column1 Column2
if B --> 2
if C --> 3


if A --> 1


Thanks
Diego
