How to write GET request content to a file with new lines instead of \n characters

I am able to parse it, however it puts the keys in quotes and still doesn’t put any new lines in the file.
After running JSON.parse in the mapper, the output looks like this:
{
“object” : {
“source_1” : “website”,
“source_2”: “website”
}
}
After JSON formatter and file writer, the saved file looks like this:
{“object” : {“source_1” : “website”, “source_2”: “website” } }
