    Normalizing historical data with a pivot table parse

    I have several historic data sets that I would like to normalize to a common structure.

    I would like to convert this:
    date |area | color | Dodge | BMW | Delorean | Ford
    12/2/2012 | London | blue | 2 | 3 | 1 | 6
    12/3/2012 | Tokyo | green | 1 | 5 | 2 | 1
    12/3/2012 | Juneau | white | 0 | 1 | 1 | 9
    to this:
    date | area | color | quantity | make
    12/2/2012 | London | blue | 2 | Dodge
    12/2/2012 | London | blue | 3 | BMW
    12/2/2012 | London | blue | 1 | Delorean
    12/2/2012 | London | blue | 6 | Ford
    12/3/2012 | Tokyo | green | 1 | Dodge
    12/3/2012 | Tokyo | green | 5 | BMW
    12/3/2012 | Tokyo | green | 2 | Delorean
    12/3/2012 | Tokyo | green | 1 | Ford
    12/3/2012 | Juneau | white | 0 | Dodge
    12/3/2012 | Juneau | white | 1 | BMW
    12/3/2012 | Juneau | white | 1 | Delorean
    12/3/2012 | Juneau | white | 9 | Ford
    Is this something that pivot table can handle?
    I confess to being a bit lost regarding how to frame this problem...even though it seems so simple!
    TIA for ideas and suggestions.

    I would say a PivotTable is better at converting from what you want to what you have in this case.
    I think it makes sense to convert it into the format you want, that way you can use pivot table on it and get all kinds of information out of it with a few clicks.
    I'll try to write some macro code soon. Unless someone beats me to it.

    I don't wish to leave you with no answer, yet I sometimes miss posts. If you feel I forgot you, remind me with a PM or just bump the thread.

    Nuts: I was hoping that there was a pivot table nuance that I was missing that would allow this in a simple and elegant manner. I am interested in your thoughts regarding a macro that does this. Thanx.

    Code is not slow but it looks awkward.
    Should do the job for you.

    Both of the proposed solutions still work like a charm ...eight years later. Thanks.

    Always good to see older suggestions still being valid and helpful!!
    1. Use code tags for VBA. [code] Your Code [/code] (or use the # button)
    2. If your question is resolved, mark it SOLVED using the thread tools
    3. Click on the star if you think someone helped you
