Conversion of json file to Reltio Specific format

Hello,
We are creating a data interface between snaplogic and reltio with a .json file.
Reltio expects the .json file to be in a specific format as below:
Notice the ‘new line’ i.e ‘\n’ inserted after every record of json data.
We tried scripts hook, regular expression with replaceAll…etc but haven’t been successful.
Any help in this regard would be appreciated.

We intend to achieve the following:

1. Loop for json records.
2. Fetch a record of json data.
   3 Append a new line / line feed / carriage return (and this should be visible in the RAW data preview too)
3. Fetch another record of json data
4. Insert this new record on a new line
5. Store the updated file as .json

Any quick help shall be highly appreciated.
