Fastest way to interface between live (unsaved) Excel data and C# objects - Stack Overflow
void AssignArrayToRange()
// Create the array.
object[,] myArray = new object[10, 10];

// Initialize the array.
for (int i = 0; i < myArray.GetLength(0); i++)
for (int j = 0; j < myArray.GetLength(1); j++)
myArray[i, j] = i + j;

// Create a Range of the correct size:
int rows = myArray.GetLength(0);
int columns = myArray.GetLength(1);
Excel.Range range = myWorksheet.get_Range("A1", Type.Missing);
range = range.get_Resize(rows, columns);

// Assign the Array to the Range in one shot:
range.set_Value(Type.Missing, myArray);

python - NumPy array/matrix of mixed types - Stack Overflow
Helps with creating numpy arrays with mixed types. However, if you're looking to combine different multidimensional numpy arrays (with several rows and columns) into one large array of mixed types, don't use numpy.column_stack method because it will convert all of them to one type (convert ints into strings for example). Rather, use pandas concat method instead, which means you turn each multidimensional array into its own dataframe.
