New Post: display a number with thousand separator in Indian style( 12, 12,34,567.89)in the exported excel sheet using program

Hi Herin,
I think the inbuilt format your looking for is "#,##0.00" as opposed to "##,##,##,##0.00"
There's a list/description of Excel's built in number formats somewhere on the web (apologies, I don't have a link) which you'll be able to use with GetBuiltinFormat

Good luck.
