How to insert " into a cell in excel

Hi,

I have a z function module to download data into excel file .

Types: begin of t_file,

line(1000) type c,

end of t_file.

I need to create an internal table of above type and send it to z function module to create excel.While creating internal table one of the fields values should be something like "2(starting with ") .During debugging I am able to see " but after download there are some junk characters in that field instead of ".

Please let me know how to send " into excel file

Thanks
