Render same comp multiple times with different text

Hi!

I am looking for a way to render my composition 100+ times with different text in two layers. I was thinking to batch replicate this comp and then batch change text layers, but I have been googling around and did not find any solutions.

I don't need ready solution, just a direction on a approach I should take to complete such task. I was told on another forum to ask here and that there are some scripts that do just what I need using excel file as data. Could you point me to them?

Thank you!
