How to modify the csv feed file in gatling

Question

I have a user.csv file like this:

user, password
userid1, password1

I want to decrypt the password in the csv file. One way is .feed(csv("user.csv")) and then

.exec(session => {
        val pwd = session("password").as[String]
        session.set("password", decrypt(pwd))//some function to decrypt the password
      })

Now I want to decrypt the password before feed the csv file. Is there any way to do that in Gatling?

Answer 1

You can add a conversion to a feeder definition with a function that will convert a given value.
