What's "rng"? How does that set_Item function look like?

Excel.Range rng = null;

Hello sonali,
Did you use any loop? Because this type of error comes when data are more then you expectation.

Solution 1

"Excel.Range rng = null;" Then I'd actually expect a NullRefereceException. Well, look at the place where you set the range to some value. And then use a "bigger" range allowing for a sufficient amount of rows and columns.
