Is there any way to read in the file (in python) and indent / pretty-print the json to a

Answer 1

Yes, you can use open() to read/write file, then json.load() to read the file and json.dump(..., indent=4) to pretty-print it.

Answer 2

Read the file using json.load(..), and use json.dump(..) to write the object out to another file while specifying indent value.

with open("inFile") as f, open("outFile", "w") as g:
    json.dump(json.load(f), g, indent=4)
