Adding multiple rows in worksheet using insertCSV function

Adding multiple rows in worksheet using insertCSV function

Hi
  I need to add 2 rows in a sheet using insertCSV function. The CSV string looks like  "Row1Col1,Row1Col2\nRow2Col1,Row2Col2"

When using this with the insert CSV function, there is only one row inserted with the entries as
Row1Col1     Row1Col2\nRow2Col1   Row2Col2

Basically the \n is not recognised as a new line character.

Where am I going wrong ?
