Save as a different format

Hi, not sure if this question is out of the forum, but here is the first site that come to my mind.
Here is my question.
I'm writing a script and batch to do monthly data downloading from a SFTP.
The downloading part is successful. However, is there a way that I can download the file and save as a different format? For example, the txt file is in ANSI and i would like to download the file and save as Unicode or vise versa.

Plesae let me know if it's doable automatically.
I appreciate your help

WinSCP does not support such conversions. But you will be definitely able to find a tool that you can run after the download to do the conversion.
