Sir, it is possible to perform operations on that. Atleast query operations. This can be done by using the xls driver. (select * from Sheet1 where blah blah). Can you Give me the syntax ....how to connect..etc Thanks and Rgds VamsiDhar.MBC SoftwareEngineer

Hai, CSV is just a text file...You cannot perform any operations on that. I think you have to Convert that text File in Table/Excel Format.. For this ..first you have to check ... 1.weather your file is variable length/Fixed length.... (...means weather your file is following any format..or not) 2.How it is parsed...(with coma,semicolon, space,tab etc) VamsiDhar.MBC SoftwareEngineer
