Hi,      Im new to Apache Nifi and i'm looking on how to filter the CSV data using specific column.        I'm able to convert to JOSN without filtering, but SplitText and RouteonAttribute processors are not helping to filter the data. Below is my input CSV.   Input: number,name,resourceState,location,manufacturer 111897,lok,INSTALLED,HYD,ABC 115677,redd,RETIRED,BLR,ABC 1108448,eswar,PROP_INITIAL,CLT,ABC 1116740,wqwq,INITIAL,AA,ABC   Filtering should be based on resourceState column to consider INSTALLED and RETIRED data. So, converted JSON should have only 2 rows like below.   Expected JSON Output: [{ "number": "111897", "name": "lok", "resourceState": "INSTALLED", "location": "HYD", "manufacturer": "ABC" }, { "number": "115677", "name": "redd", "resourceState": "RETIRED", "location": "BLR", "manufacturer": "ABC" }]   Please help me on the CSV filtering part.   Thanks in Advance. ...
