CSV problem when i try to read it

Hello community, my problem is when i try to open a downloaded csv that has a dynamic number throws this error:

Main has thrown an exception

Source: Read CSV

Message: The CSV file format for X:\Descargas\peajes-interurbanos-facturados-0003617963.csv is invalid

Exception Type: Exception

System.Exception: The CSV file format for X:\Descargas\peajes-interurbanos-facturados-0003617963.csv is invalid
at UiPath.Core.Activities.ScopeActivity.OnFaulted(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)
at System.Activities.Runtime.FaultCallbackWrapper.Invoke(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)
at System.Activities.Runtime.FaultCallbackWrapper.FaultWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

this is how i send the path:

“X:\Descargas”+excelPrefijo+numFactura+".csv"

translated is:
Read CSV : The CSV file format for X:\Descargas\peajes-interurbanos-facturados-0003617963.csv is invalid

and this csv exits :confused: and if i open this “X:\Descargas\peajes-interurbanos-facturados-0003617963.csv” with the console or something the file is open . Any idea?

By looking the Exception, it is saying File Format is not valid.

Have you tried to open it in Excel or Notepad?

The problem was the delimitator, so was comma and i changed to semicolom
