Hi Tom

I'm trying to test unique data scenarios within a set of data

The data has lets say 10 columns and column can have a few variants (eg Yes,No,?,etc..)

Can I setup a macro that lists out the unique scenarios combining the variables and their variants?

As a side question how would I calculate the no. of unique combinations using math?

Thanks in advance for your help

Bob

Bob,

If you want to know how many combinations you would have, then assume

A 10

B 5

C 7

E 2

so you would multiply the number of variants 10 x 5 x 7 x 2 = 700

You can see with 10 columns this would get big fast.

as far as writing them out with vba, yes you could do this

Sub abc()

Dim v, i As Long, j As Long, k As Long, l As Long, m As Long

Dim n As Long, o As Long, p As Long, q As Long, r As Long

Dim max As Long

ReDim v(1 To 10)

For i = 1 To 10

v(i) = Cells(Rows.Count, i).End(xlUp).Row

Next

max = 0

For i = 1 To 10

If max < v(i) Then

max = v(i)

End If

Next

max = max + 2

For i = 1 To v(1)

For j = 1 To v(2)

For k = 1 To v(3)

For l = 1 To v(4)

For m = 1 To v(5)

For n = 1 To v(6)

For o = 1 To v(7)

For p = 1 To v(8)

For q = 1 To v(9)

For r = 1 To v(1)

Cells(max, 1) = Cells(i, 1)

Cells(max, 2) = Cells(j, 2)

Cells(max, 3) = Cells(k, 3)

Cells(max, 4) = Cells(l, 4)

Cells(max, 5) = Cells(m, 5)

Cells(max, 6) = Cells(n, 6)

Cells(max, 7) = Cells(o, 7)

Cells(max, 8) = Cells(p, 8)

Cells(max, 9) = Cells(q, 9)

Cells(max, 10) = Cells(r, 10)

max = max + 1

Next r, q, p, o, n, m, l, k, j, i

End Sub

That assumes 10 columns in A:J with variants starting in row 1
