@stevenmatison Thanks a lot for your reply. very much appreciated. I tried it but got stuck in the ExtractText processor. My real file consists of 13 columns and #4 is the relevant one with the needed value. The input Flow File that feeds the ExtractText processor looks like this: #4 is value 25.0 (before "cpm") Meanwhile i removed the headers since i was not sure if that has got an impact or not. So what i did next in ExtractText processor is creating a new property named Value: ,,,(.*?),,,,,,,,, But when i run the workflow all the flow files goes unmatched off the ExtractText processor. So there are no matched ones that go to RouteOnAttribute. I really don't know what went wrong here. Thank you & Regards
