Hello @SAMSAL I have used ExtractText processor. This processor has an inbuilt property "Search Value" which I filled as ^(.{5})(.{10}) and in property "replacement value" as $1,$2 My Extract Processor conf is below I also want to have whitespaces in my address. like if it is: smithAb Cd 12345678 then i want user name to be smit and address to be Ab Cd 1234. Also I want to point out that I am basically constructing a comma separated flowfile by using this. The comma "," in $1,$2 makes them comma separated at the end. The issue is that all works fine but this last $2 is not limiting to only 10 chars but taking chars after the 10 char also. so it ultimately becomes Ab Cd 12345678 instead of Ab Cd 1234 As I was speaking of some experimentation, I observe that if I do "Search Value" which I filled as ^(.{5})(.{10})(.{1}) and in property "replacement value" as $1,$2,$3 then I observe that both username and address comes proper as expected. now this $3 replaced value contains the extra until last characters.
