Ignore duplicates and create new row of unique values in excel?

[iamkris10jenn]

I have seen this question asked and answered in various forums with columns of data, but never rows of data. Modifications I have tried have not worked for me.

I have several rows (>5,000) containing values in columns A-G that often appear as duplicates. I need to create a horizontal list of unique values in columns I-O based on the first set of values, as follows...

	A	B	C	D	E	F	G	H	I	J	K	L	M	N	O
Row 1	1	1	2	2	3	3	4		1	2	3	4
Row 2	1	2	1	1	1	1	1		1	2
Row 3	3	4	3	3	2				2	3	4
Row 4	1	2	3	4	5	6	7		1	2	3	4	5	6	7
.
.

<tbody>
</tbody>

The unique list doesn't need to be in order, but does need to be next to the original data (there is other associated data in additional columns) and I'm not able to paste/transpose, filter, etc. as the information in this sheet changes regularly. The values listed above are numbers for ease of reading but the actual data in each cell is alphanumeric (e.g. 7AGG00123). This should be accomplished via formulas (no VBA please).

Any help is appreciated!!

Are the data items numeric as shown or can they be anything?

They are a mix of numbers and text, usually something that looks like this: 7AG-G008-04

I1, control+shift+enter, not just enter, copy across, and down:

=IFERROR(INDEX($A1:$G1,SMALL(IF(FREQUENCY(IF($A1:$G1<>"",
  MATCH($A1:$G1,$A1:$G1,0)),Ivec),Ivec),COLUMNS($I1:I1))),"")

Ivec is defined using Formulas | Name Manager as referring to:

=TRANSPOSE(COLUMN(Sheet1!$A$1:$G$1)-COLUMN(Sheet1!$A$1)+1)

Adjust the sheet name to suit.
