    List down all possible combination ( alphanumeric) from table of data

    Hi,

    Im so sorry if Im posting at the wrong sub-forum.

    I have to list down all possible combination from table of data.
    Attached is sample of data and output that Im looking for.

    I have tried using Microsoft Queries - but no luck.
    May be due to data limitation.

    Please help me.

    Do you realise how many combinations that will yield? Put this formula in B2:

    =COUNTA(B4:B25)

    and copy that across into C2:T2. It will give you the number of items in each column. Then you can put this formula in A2:

    =PRODUCT(B2:T2)

    It will give you the answer of 4.1E15, i.e. 4.1 times 10 raised to the power 15. Excel has just over 1 million rows per sheet (i.e. 10 to the power 6), so you would need over 1 billion sheets (10 to the power 9) to list them all.

    If you want to see how you could do this with a much smaller data set, take a look at this thread:

    Hope this helps.

    Pete

    I thought you must have abandoned the attempt ...
