(ChatGPT) Give me codes to generate Sudoku 9x9 number array in VBA

Sure! Here is some sample VBA code that you can use to generate a 9x9 Sudoku number array:

Sub GenerateSudoku()

Dim sudoku(1 To 9, 1 To 9) As Integer

' Initialize the Sudoku array with zeros
For i = 1 To 9
    For j = 1 To 9
        sudoku(i, j) = 0
    Next j
Next i

' Generate the Sudoku puzzle
GeneratePuzzle sudoku

' Print the Sudoku puzzle to the sheet
PrintPuzzle sudoku

End Sub

Sub GeneratePuzzle(ByRef puzzle As Variant)

' Your code for generating the Sudoku puzzle goes here

End Sub

Sub PrintPuzzle(ByRef puzzle As Variant)

' Print the puzzle to the sheet
For i = 1 To 9
    For j = 1 To 9
        Cells(i, j).Value = puzzle(i, j)
    Next j
Next i

End Sub

The GeneratePuzzle function is where you would put your code for generating the Sudoku puzzle. You can use various techniques, such as backtracking or constraint satisfaction, to fill in the puzzle with valid numbers.

The PrintPuzzle function is a simple helper function that prints the puzzle to the sheet, so you can see the generated puzzle.
