@manuboss Parse Line (deprecated) - doesn't mean it's unusable, it's still usable if you want.
Or you can use an alternative method called "Parse CSV string"
You asked this question, I think you are new, and the message cannot tell you all about your problem, because there is a lot of information as well as different use cases.
So you can follow the basic instructions.
This will fall in the same lines at the LinesFromFile but instead of Use Only Once, you will use them Unlimited if they are changing every X minutes. You can also add a WAIT to the usage of milliseconds after adding the resource. 300000 = 5 minutes
