I have 3 different sets of data (in different columns)

  1. Animals (5 different kinds) in column A
  2. Fruits (1000 different kinds) in column B
  3. Countries (10 different kinds) in column C

With these 3 data collections I would like to receive 5×1000×10 for a total of 50k corresponding elements in col. E F G (each animal who corresponds with each fruit and each country).

It might be done by manually copying and pasting values, but it will take ages. Is there any way to automate it by VBA code or

Is there any universal formula for unlimited data sets like the one presented above? Please let me know if something is not clear.

Here is a smaller example of data and how the results should turn out:

        

My first approach to this problem was similar to the one posted by @Jeeped:

  1. load input columns to array and count rows in each column
  2. fill array with all combinations
  3. assign array to output range

Using MicroTimer I have calculated average times taken by each part of the above algorithm. Part 3. took 90%-93% of total execution time for bigger input data.

Below is my attempt to improve the speed of writing data to worksheet. I have defined a constant iMinRSize=17. Once it is possible to fill more than iMinRSize consecutive rows with the same value, the code stops filiing array and writes directly to worksheet range.

  Dim iArrLastC As Integer

  iArrLastC = 1
  ReDim iLengths(1 To iCCnt)
  For i = 1 To iCCnt
    j = iRSrcCnt
    While (j > 0) And IsEmpty(vSrc(j, i))
      j = j - 1
    Wend
    iLengths(i) = j
    iRTrgCnt = iRTrgCnt * iLengths(i)
    If (iRTrgCnt < iMinRSize) And (iArrLastC < iCCnt) Then iArrLastC = iArrLastC + 1
  Next i

  If (iRTrgCnt > 0) And (rTrg.row + iRTrgCnt - 1 <= rTrg.Parent.Rows.Count) Then
    ReDim vTrgPart(1 To iRTrgCnt, 1 To iArrLastC)

    iStep = 1
    For i = 1 To iArrLastC
      k = 0
      For j = 1 To iRTrgCnt Step iStep
        k = k + 1
        If k > iLengths(i) Then k = 1
        For l = j To j + iStep - 1
          vTrgPart(l, i) = vSrc(k, i)
        Next l
      Next j
      iStep = iStep * iLengths(i)

    rTrg.Resize(iRTrgCnt, iArrLastC) = vTrgPart

    For i = iArrLastC + 1 To iCCnt
      k = 0
      For j = 1 To iRTrgCnt Step iStep
        k = k + 1
        If k > iLengths(i) Then k = 1
        rTrg.Resize(iStep).Offset(j - 1, i - 1).Value2 = vSrc(k, i)
      Next j
      iStep = iStep * iLengths(i)
    Next i
  End If

  Application.ScreenUpdating = True
  Application.EnableEvents = False

Sub test()
  CrossJoin Range("a2:f10"), Range("k2")
End Sub

If we set iMinRSize to Rows.Count, all data is written to array. Below are my sample test results:

The code works best if input columns with highest number of rows come first, but it wouldn't be a big problem to modify code to rank columns and process in right order.

I gather by universal, you want this to accommodate any number of columns and any number of entries in each. A few variant arrays should provide the dimensions necessary to calculate the cycles of repetition for each value.

Put the column header labels in row 2 starting in column A and the data directly below that.

I have added some error control to warn of exceeding the number of rows on a worksheet. This is not normally something that is likely to be a consideration but multiplying the number of values in an undetermined number of columns against each other can quickly produce a large number of results. It is not unforeseeable that you would exceed 1,048,576 rows.

If you want to apply AutoFit to an entire spreadsheet, click "Select All" in the "Edit" menu. For Each cell In Range("B2:B" & LastRow) As an observation the code is a bit lacking inconsistency. the coder uses With Worksheets(sSheetName) but then defines sheetname as the active sheet so the WITH statement isn't necessary as it would work on the active sheet without that.

Classic example of a non-join select SQL statement which returns the Cartesian Product of all combination outcomes of listed tables.

SQL Database Solution

Simply import Animals, Fruit, Country as separate tables into any SQL database like MS Access, SQLite, MySQL, etc. and list tables without joins including implicit (WHERE) and explicit (JOIN) joins:

SELECT Animals.Animal, Fruits.Fruit, Countries.Country
FROM Animals, Countries, Fruits;

Excel Solution

Same concept with running the non-join SQL statement in VBA using an ODBC connection to workbook containing ranges of Animals, Countries, and Fruits. In example, each data grouping is in its own worksheet of same name.

Sub CrossJoinQuery()

    Dim conn As Object
    Dim rst As Object
    Dim sConn As String, strSQL As String

    Set conn = CreateObject("ADODB.Connection")
    Set rst = CreateObject("ADODB.Recordset")

    sConn = "Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};" _
               & "DBQ=C:\Path To\Excel\Workbook.xlsx;"
    conn.Open sConn

    strSQL = "SELECT * FROM [Animals$A1:A3], [Fruits$A1:A3], [Countries$A1:A3] "
    rst.Open strSQL, conn

    Range("A1").CopyFromRecordset rst

    rst.Close

How do I expand all columns in Excel spreadsheet?, Click where the row and column headers meet, this will select the entire sheet, like so: alt text. Then double-click any one of the column partition lines. I do this all  Select any cell in the column/row you want to autofit: To autofit multiple non-adjacent columns/rows, select one column or row and hold down the Ctrl key while selecting the other columns or rows. To autofit the entire sheet, press Ctrl + A or click the Select All button.

You can do this with worksheet formulas. If you have NAME'd ranges -- Animals, Fruits and Countries, the "trick" is to generate indexes into that array to provide all the various combinations.

For example:

=CEILING(ROWS($1:1)/(ROWS(Fruits)*ROWS(Countries)),1)

will generate a 1-based series of numbers that repeats for the number entries in Fruits * Countries -- which gives you how many rows you need for each animal.

=MOD(CEILING(ROWS($1:1)/ROWS(Countries),1)-1,ROWS(Fruits))+1

will generate a 1-based series that repeats each Fruit for the number of countries.

=MOD(ROWS($1:1)-1,ROWS(Countries))+1))

Generates a repeating sequence of 1..n where n is the number of countries.

Putting these into formulas (with some error checking)

D3:  =IFERROR(INDEX(Animals,CEILING(ROWS($1:1)/(ROWS(Fruits)*ROWS(Countries)),1)),"")
E3:  =IF(E3="","",INDEX(Fruits,MOD(CEILING(ROWS($1:1)/ROWS(Countries),1)-1,ROWS(Fruits))+1))
F3:  =IF(E3="","",INDEX(Countries,MOD(ROWS($1:1)-1,ROWS(Countries))+1))

Actually, I want to modify my old answer. But, my new answer is fully differ from old answer. Because, old answer is for specific column and this one is for universal column. After answering the old answer, the questioner say new requirement which he want to do it in universal. For fixed column, we can think fixed looping and for infinite column, we need to think from another way. So, I also do it. And SO users also can see the code differences and I think, this will be helpful for beginners.

This new code is not so simple like the old one. If you want to know clearly about code, I suggested for debug the code in line by line.

Don't worry about the code. I already tested about it in step by step. It perfectly work for me. If it is not for you, please let me know. One things is that this code can cause error for blank row(which has no data). Because, currently, I not added checking for that.

How to AutoFit in Excel: adjust columns and rows to match data size, This option expands the row vertically to hold multi-line or extra-tall text. To AutoFit column width, select one, several or all columns on the sheet, way to accommodate long text is to merge several cells into one big cell. Firstly type the formula of =(A1*3+8)/5 in Cell C1, and then drag the AutoFill Handle down to the bottom in Column C, then the formula of =(A1*3+8)/5 is applied in the whole Column C. If you need to apply it to the entire row, you can drag the AutoFill Handle to the far right.

  • Your description of your desired outcome is a bit vague to me. Could you clarify by uploading just a small sample of a few rows in excel. If I say you just want to copy column A,B, and C into E,F and G am I right then?
  • Hello. I posted. Providing the link: filedropper.com/xmplso Please take a look.
  • I added a printscreen in your question. Is there a reason why every summary row is there twice?
  • Actually nope. Adding screenshot with modified example. Thank you for noticing that
  • Does gorilla get combined with apple as well, or just with banana?
  • This is the winner both for speed and thoroughness. Thanks for taking the time to explain and demonstrate the speed tests.
  • The VBA you wrote for this is superfast and I plan on looking at it more closely; however, when I ran the macro based on the opportunities actual data set (5 Animals, 1000 Fruits, 10 Countries), I got a Run-time error 6: Overflow.
  • Thanks for finding that. I had to wrap a division operation in brackets to gain mathematical precedence before a multiplication operation. See this. I'll be adding some error control and that math formula fix to this post in a short while.
  • Minus 1 for merging cells. Kidding! (I do it all the time) I was trying to write this from scratch at 1:00 AM and I couldn't process the math. The line in the code that was previously throwing the exception is what I couldn't come up with.
  • Hello Jeeped. Thank you for your effort. Seems your macro works perfectly for 3 data sets - I've tried already and it's really amazing. For 802x198x4 data set of 635184 rows were returned in nearly 5 secs! Extremely odd! Many thanks for it! Also tested for 4 and 5 columns and works perfectly. Just it seems the only limitation now is excel workbook
  • @mysticous Do you think Excel's row limitation is ever going to be an issue for you when running this procedure? In other words, are there going to be circumstances when the output could be well over a million rows?
  • Hello. Thank you for this solution. You can also do this as cross join, but let's say user is not accessible to solve this issue through MS SQL or Access
