I have created an array in VB and want to copy the whole array to an excel spreadsheet rather than doing it a line at a time. This will make the process much quicker.

The array code at VB end is like as follows

VB

xlWorkSheet.Range("A2").Resize(x, y).Value = MyArray

The excel spreadsheet has headings

Name, Dept, Salary

Rather than being dispalyed as

Name     Dept        Salary
Smith    Accounts    10000
Green    Sales       14500 
Brown    Accounts    12000

It is getting displayed as

Name       Dept   Salary
Smith      Green  Brown
Accounts   Sales  Accounts
10000      14500  12000

There must be a simple solution?

MyArray is made up as follows 3 elements and say 1000 records

i.e. MyArray(3,1000)

What you've got should work, assuming that A2 is your starting cell, and that x and y are the lengths of your array dimensions. More generically,

VB

xlWorkSheet.Range("A2").Resize(MyArray.GetUpperBound(0) + 1, MyArray.GetUpperBound(1) + 1).Value = MyArray

Be aware that there is (or was) an unadvertised limit on the cell size when populating via an array. Used to be that if your data was more than 912 characters, it'd get left blank. Way to handle that was to check your array for such instances and replace them with some dummy value, storing the indices, and then after you've loaded the sheet, go back through and replace the dummy values. That was an older version of Excel (maybe 2007?), so that may be fixed now.

Looking at your results, I'm guessing your array is loaded wrong. Take a look at the data in the array before your put it in the sheet.
