my one processor output is a flow file which contains text lines , each line is having semicolunm , i would like to split each line into mulitple lines .
I think you need to use SplitText and SplitContent. SplitText can split lines, then pass each line to SplitContent, which can be configured delimiter by hexadecimal format as "Byte Sequence". Semicolon ";" is "3B".
