Adding linebreak to json written by Python
From this answer try outputdict = json.dumps(outputdict, indent=4) with the number of spaces you want to indent.
It sounds like its a 'Carriage Return' + 'Newline' issue which will cause the file to open as one long line in a Windows text editor.
Try:
with open("filename.json",'w', newline='\r\n') as f:or:
with open("filename.json",'w', newline='\n') as f:or there may even be a setting in your Text Editor to correct this issue.
