<p>I am having trouble in exporting to excel and it crashes out at the .set_Value function.</p>

<p>It seems to work if I change object[,] to string[,] but by doing this I lose the formatting.</p>

<p>Anyone Help?</p>

Are you passing '
```
null
```
' for missing parameters rather than
```
System.Reflection.Missing.Value
```
?
