Any open Source for File transformation

[Senthil Kumar Sekar]

Is there any open source API available in market for the below purpose.

I will have input CSV file from which i need to extract data from certain positions and place it a specific position in output CSV(which is new one).

Later on i might have different input and output formats But for now i have CSV as the supproted formats.

Any suggestions for this.Do we have any open API existing for this?


I am not sure if i am using correct terminology and unable to fetch results from google.

Thanks.
