Formula to extract unique records only

[hrayani]

Hi,

I need a formula to extract only the first occurrence of the data or unique records I can say. The formula should
look all the 3 columns in a row and should treat it as a duplicate if all the 3 cells are equal - otherwise not.

here is a sample data in A2:C17

Article	Quality	Unit
AA	1	Kgs
BB	2	Pair
DD	3	Dozen
EE	4	Grams
AA	1	Kgs
BB	2	Pair
AA	1	Kgs
AA	1	Kgs
DD	3	Dozen
AA	3	Pair
AA	5	Dozen
AA	5	Grams
AA	1	Kgs
AA	1	Kgs
AA	1	Kgs
AA	1	Kgs

<colgroup><col width="64" span="3" style="width:48pt"> </colgroup><tbody>
</tbody>

unique data required in columns H2:J17

in the above case the answer in H2:J17 would be

Article	Quality	Unit
AA	1	Kgs
BB	2	Pair
DD	3	Dozen
EE	4	Grams
AA	3	Pair
AA	5	Dozen
AA	5	Grams

<colgroup><col width="64" span="3" style="width:48pt"> </colgroup><tbody>
</tbody>

Rest all rows till 17 will show blanks as there is no more unique data.

If any one can provide a solution

Regards,

Humayun

Copy A1:C17 to H1:J17, go on data tab and click remove duplicates (then tick "my data has a header")

Thanks for reply,

Yes i can do that manually but i need a formula to do that coz the actual data will keep on adding. So if there is a formula then i do not have to remove duplicates manually everytime....

I found one formula which works for a single column....

=IFERROR(INDEX($A$2:$A$17, MATCH(0,COUNTIF($H$1:H1, $A$2:$A$17), 0)),"")

but i dont know how to get it to work for 3 columns...

Any Idea ???

Hello,

In cell H2 ... test following Array Formula:

=IFERROR(INDEX(A$2:A$17,MATCH(0,COUNTIF($F$1:F1,$A$2:$A$17&$B$2:$B$17&$C$2:$C$17),0)),"")

Hope this will help

It is possible with an array formula {}, but could not find it yet.
A better solution than formulae going down and showing "" if error is to set this data in a table (so range extend automatically, no need to update the source), make a pivot

(tabular form) ​

of the table in h1 putting Article, quantity and unit in rows and refresh the pivot automatically when you activate the sheet:
right click sheet name, click view code and paste

Private Sub Worksheet_Activate()
ActiveWorkbook.RefreshAll
End Sub

Hi James,

I tried it... All it is giving the first cell value in all the cell till row 17

The formula wont do down more than 70 rows... coz there will not be more than 70 unique values... Yes the actual data currently runs at over 600 rows and will be increasing everyday.

I am not familiar with tables and pivot..

Yes u r right... I am hopefull i will get one here

Hello,

You can test following:

Sub Unique3Cols()
    With Worksheets("Sheet1")
        .Range("A1:C17").AdvancedFilter Action:=xlFilterCopy, CopyToRange:=.Range("H1:J1"), Unique:=True
    End With
End Sub
