Retaining the Unix CSV format in Excel format while exporting

Hi All,
I have created a Unix Shell script whch creates a *.csv file and export it to Excel.
The problem i am facing is that Users wants one of the AMOUNT field in comma separted values. Example :
if the Amount has the value as 3000000 User wants to be in 3,000,000 format.

This Amount format i am using in Unix script but once it is exported to Excel the format gone and i am not getting the required format.

Any help would be useful here.

Hi,

Try to put double quotes around the amount "30,00,00".

Thanks that work for me.
One quick query again: is it possible to have AutoFilter in all the fields when it is open in Excel.
