Concatenate Break Formula

[Craig Naylon]

Hi,

The below table represents what I am currently doing manually but would am trying to come up with a formula to do for me. Or, some combination of formulas to get to the result I need.

I need to write the result in the HTML column Currently I'm using the concatenation formula in the Formula column. It is simply concatenating the html tags and the data in the Description column for every cell where the Prod Ref # is the same. I'm copying / pasting the formula into the cell where the next Prod Ref # changes and removing the cell references or adding cell references as necessary to the formula. It's VERY time consuming and inefficient.

I have a .xls with 10,000's of lines. I can't figure out how to automatically break and start a new concatenation formula as the Prod Ref # changes.

Any Suggestions?

Thanks.

Prod Ref #	Description	Formula	HTML
201000	DESC1	'=CONCATENATE(" ",B2," ",B3," ",B4," ",B5," ",B6," ",B7," ")	DESC1 DESC2 DESC3 DESC4 DESC5 DESC6
201000	DESC2
201000	DESC3
201000	DESC4
201000	DESC5
201000	DESC6
201002	DESC1 <tbody> </tbody>	'=CONCATENATE(" ",B8," ",B9," ",B10," ")	DESC1 DESC2 DESC3
201002	DESC2 <tbody> </tbody>
201002	DESC3 <tbody> </tbody>
201004	DESC1 <tbody> </tbody>	'=CONCATENATE(" ",B11," ",B12," ",B13," ",B14," ",B15," ")	DESC1 DESC2 DESC3 DESC4 DESC5
201004	DESC2 <tbody> </tbody>
201004	DESC3 <tbody> </tbody>
201004	DESC4 <tbody> </tbody>
201004	DESC5 <tbody> </tbody>

Use two formulae. Column C to build up the concatenation, and column D to only show it on the first row of a product.
Put these formulae in C2 and D2, then copy down:
=B2&IF(A2=A3,C3,"")
=IF(A1=A2,"",C2)
