## Extract unique distinct values from a related table

In a previous post I described how to do lookups in a related table. In this post I am going to show you how to extract unique distinct values and duplicates from a related table.

In these two examples there are two tables and they have a column in common (Company).

in excel sheet

i need to search three different word in eight sheet in particular cell and paste if present other wise blank

Example EE2203A,EE2204B,ME2201C

if present of any one paste EE2204B, other wise blank

karthikeyan,

can you explain in greater detail?

Hi Oscar,

You helped me out in the past, and I'm trying to understand the =Index(Match functions in an Array formula.

I have a range of data in 2 different columns on Sheet 2.

The ranges are almost identical, so much so that a simple "If" statement can show me differences.

. If they are equal display 1 else dispay 0. I don't want to filter as there is other data records in the sheet that are used in a vlookup formula.

So what would be the easiest way to have my first sheet "Sheet 1(A2)" find the "0" cells on Sheet 2 and display the values which are offset by 1 row?

In other words, for each two records on Sheet 2 that don't match, create a list of the 2nd record on "Sheet 1" with no blanks in between them.

Thanks in advance!

Hi Oscar,

This is a question specific to your other article "How to extract a unique distinct list from a column in excel," but there wasn't a section to leave a reply, so I will ask it here.

I'm using your vba code for a user-defined function to extract unique distinct sorted values, but I want to use it in a table. As you probably know, multi-cell array formulas are not allowed in tables, so is there a way around this?

Thanks!

Hi Oscar,

I used your formula above, i have a question, it is possible to have a two search criteria?

Julius,

Yes it is.

Array formula in cell B21:

=IFERROR(INDEX(Table2[Sales persons], SMALL(IF((ISERROR(MATCH(Table2[Company], IF(COUNTIF($B$19:$C$19, Table1[Item]), Table1[Company], ""), 0)))+COUNTIF($B$20:B20,Table2[Sales persons]), "", MATCH(ROW(Table2[Company]), ROW(Table2[Company]))), 1)), "")

Hi Oscar,

I have two different tables, some row in both tables have same data, i want to extract unique rows data by comparing both tables... How can I do this...?

Hello Kamran Mumtaz

7 8

9 10

11 12

13 14

15 16

19 20

I have a large data file 8000x10 and the numbers are pair the first two number in first row will become first 2 numbers in first row , third and four in row 1 will be first and second in row 2, etc.
