How to autodetect format for each csv file

Hi,

I am creating a wokflow where i need to deal with csv that are sent by email by clients. But it’s not always the same format. I have a loop with the node csv reader :

But my problem is that my csv files doesn’t have the same cells separators. If I press the autodetect format button it works but for the next iteration it might not. Is there not a way to automatically autodetect the format of my csv each time ?

Thanks for your help !
