Interesting and complicated problem, need vba help on processing multiple columns of data into rows

[spyrule]

hello,
I've got an interesting problem to solve. I've got a worksheet that will be re-used repeatedly to take raw automotive data and "convert" that data into a specifically formatted text output on another sheet.

Here is a sample source table of the data I have to process:

​

Source Sheet:​

​

SKU	YEAR	MAKE	MODEL	SUB-MODEL
ProductA	2006-2013|2005-2009	Audi|Volkswagen	A3|GTI
ProductB	2002-2007;2008|2006-2010	Subaru|Mitsubishi	Impreza;Legacy|Lancer	2.5i,WRX,STi;GT,SpecB|GS

<tbody>
</tbody>

Here is what the output should be like:

​

Destination Sheet:​

SKU	YEAR	MAKE	Model	Sub-Model
ProductA	2006-2013	Audi	A3
ProductA	2005-2009	Volkswagen	GTI
ProductB	2002-2007	Subaru	Impreza	2.5i
ProductB	2002-2007	Subaru	Impreza	WRX
ProductB	2002-2007	Subaru	Impreza	STi
ProductB	2008	Subaru	Legacy	GT
ProductB	2008	Subaru	Legacy	SpecB
ProductB	2006-2010	Mitsubishi	Lancer	GS

So as you can see, this is a lot of text processing with several different rules.

1) The sheet can have anywhere from 1 to 100,000 rows of data like this. The columns themselves WILL NOT be in this order, but will be spread out, and will have Named Ranges applied to each column for easy "grabbing" of that chunk of data.
2) The Pipe symbol will always designate a major separation of Year/Makes/Model/Sub-Models (YMMS). Meaning if a pipe symbol is encountered, it should be expected to find a matching pipe symbol in the rest of the YMMS columns.
3) semi-colons are used as symbol to split data within the same piped sequence.
4) commas are used to indicate that each piece of data between the commas will require a new line of data.
5) If there is commas and/or semi-colons encountered and there is no matching option in the next column over, leave the value blank, and start the next destination row.
6) If there is NO comma and/or semi-colons specified in the previous column, then re-use the same value within the same pipe segment.
7) I'm sure I'm missing a rule atm (its 1AM and I'm wiped).

I'd love to hear from people on what they think might be the best/most efficient way to handle this problem, hopefully with some sample code ideas.

Thanks in advance,

Spyrule.

These look an awful lot like what you're trying to do.

Excel VBA - Comma Delimited Cells to Rows - Stack Overflow

Does that help get you started??

So the first one really isn't relevant to this problem, it is more about chunking alt-enter values in a single cell into multiple row (which I guess could be modified to use comma seperated values).
The second link, however does seem to reference some of what I need, except that it only supports a single column of data. I might have to approach it with a bunch of arrays, or possibly a 3+ dimensional array (which I dont really know how to do, and will have to research it).
