I'm trying to figure out how best to go about doing something im not familar with.

I've got a web based program that creates a csv file. That file needs to be opened, its data analysed, and rewritten into a differint format *.txt. Finally the new file needs to be imported into another web program.

Right now I have a visual basic 2008 app that handles doing this, but im thinking a better answer is pushing that vb app into a web page. What I dont know, is what language is used to code something like that.

Would greatly appreciate some advice.
