Reading single row in csv file

[Ward]

Hi,

Is it possible to select and read a single row in a csv file?

I have a csv document with the text of all my alarms (automatic generated so that's why i start from this file source) and now i want only read the row with the corresponding alarm. So for example if my input for temperature alarm is high i want to read row 6 of the csv file and log it in a database.

I only find a way to read the whole file.

Thanks at advance!
Kind regards,
Ward

You don't have to read all the lines, just let them all be send and use a switch node to filter for your needs.

See this example flow:
