How to replace a Jason attribute value using NIFI

[#1]

I have to migrate data from Prod to test .But, My prod data has sensitive information in the Json file. I want to replace values of dozen sensitive fields with random data. How can I accomplish that using NIFI

For example the following SSN value should be replaced with 11111, etc

,"ssn":"5010040000022626666666",

"name":"john" should be replaced with bob , etc

Your help is appreciated

Thanks

We need to configure demarcator as newline (i.e shift+enter or \n)

Thanks @Shu . For some reason, I was earlier caught up that some text needs to be entered.It didn't strike in my mid that an empty line can be used. I tried above and it works totally fine. Thanks a Lot.You are awesome

Thanks @Shu for promptly responding. My issue is slightly different

It has various records in the same file because merging few Json files. For example,

[{"account":{"id":1}},{"account":{"id":2}}]

[{"account":{"id":3}},{"account":{"id":4}}]

[{"account":{"id":5}},{"account":{"id":6}}]

It works for the first line 1,2 but not for 3,4 ,5,6.
