    duplicate rows based on cell value

    Hey folks,
    I have a dataset that consists of roughly 4000 observations and I need to expand it so that I duplicate rows based on the value noted in the final column.

    Here is a sample of what my data looks like:

    Community Zone Population size Date Event Count
    B SLZ 446 03/27/2006 ILI 5
    B SLZ 446 04/03/2006 ILI 4

    And I'd like for it to look like this:

    Community Zone Population size Date Event Count
    B S 400 03/27/2006 ILI 5
    B S 400 03/27/2006 ILI 5
    B S 400 03/27/2006 ILI 5
    B S 400 03/27/2006 ILI 5
    B S 400 03/27/2006 ILI 5
    B S 400 04/03/2006 ILI 4
    B S 400 04/03/2006 ILI 4
    B S 400 04/03/2006 ILI 4
    B S 400 04/03/2006 ILI 4

    Does anyone know how I can do this using Excel 2003?

    Thanks!

    Here is one approach, assumes your data in A to F with header in row 1.

    Re: duplicate rows based on cell value

    Thanks so much for the reply!
    I'm getting an "application defined/object defined error".

    The following line is highlighted:
    Range("A" & Rows.Count).End(xlUp)(2).Resize(v(i, 6)).Value = v(i, 1)

    Re: duplicate rows based on cell value

    Just a thought but could this be because I have entries where the count is Zero?

    If this is the case, is there any way of keeping/skipping these rows and moving on to cases where the count is not zero?

    Yes but what do you want to happen to those entries?

    Re: duplicate rows based on cell value

    I'd like to have them still visible within the dataset. I don't want them to be deleted just yet.

    Thanks!

    It gives an error at the following line:
    n = IIf(v(i, 6) = 0, 1, v(i, 6))

    "Type mismatch error"

    Can you post a workbook please, and you should use code tags.

    Re: duplicate rows based on cell value

    Funny, I just ran my code on your file and it worked. Did you try on a different file?

    EDIT: the error suggests a text entry in column F.

    Re: duplicate rows based on cell value

    ya, it was a different file (I sent a smaller version). I also ran the code on this file and if you look at the output, instead of generating 5 entries for the first date, it generated a bunch more.
    Did it work properly for you?

    Re: duplicate rows based on cell value

    I noted a missing entry in the count, and deleted it. Other than this there aren't any non-numerical entries that I could see within the F column. I reran the code again and got a different error:

    Run-time error '1004':
    Application-defined or object-defined error

    When I debug the following line is highlighted in yellow:
    Range("A" & Rows.Count).End(xlUp)(2).Resize(v(i, 6)).Value = v(i, 1)

    When I run this code it goes from 208 rows to 944.
