Excel find duplicates in two tables and display related data - excel

Question

Let's say I've got two tables with two columns. In both cases, the first column consists of a name and a second column consist string of characters with the similar pattern. It looks like this:
Table 1
Peter xxxxx01
John xxxxx01
Bill xxxxx01
William xxxxx01
Table 2
Richard xxxxx02
John xxxxx02
Bill xxxxx02
Arthur xxxxx02
Now, I'd like to compare these two tables, find values where the names are duplicated and display data stored in second columns, just like this:
(Peter excluded)
John xxxxx01 xxxxx02
Bill xxxxx01 xxxxx02
(William, Arthur excluded)
I am familiar with pivot tables, however, it won't allow doing this.
I've also tried messing with index match formulas but without much success.
Any advices?

Answer 1

You can use the VLOOKUP function for this.
If your "Table1" is in B3:C6, and your "Table 2" is in F3:G6, then you can use the following formula in D3:D6 to lookup the values in table 2;
Cell D3: =IFERROR(VLOOKUP(B3,$F$3:$G$6,2,FALSE),"")
This is first looking up the name in table 1 (Cell B3) against table 2 (F3:G6), and returning the second column of table 2 if it finds the name. If it doesn't find the name, it will return an error, so we wrap the VLOOKUP in an "IFERROR" function, and replace any errors with an empty string, so it looks a bit friendlier. This results in the following table;
A B C D E F G
1
2 Table 1 Result Table 2
3 Peter xxxxxx01 Richard xxxxxx02
4 John xxxxxx01 xxxxxx02 John xxxxxx02
5 Bill xxxxxx01 xxxxxx02 Bill xxxxxx02
6 William xxxxxx01 Arthur xxxxxx02
You can then filter on the (Non-Blanks) in column D to only get the results you're interested in.
