Given "JSONlike" data this code adds the proper tabs and newlines

!Json_Tabifier.md

Given ugly json like data these programs add the proper tabs and line returns for nice formatting. Based on code https://tools.arantius.com/tabifier

Given input like this(A nested dictionary priettyprinted with pprint in python):

{   'name': '?',
	'path': '?',
	'hostname': 'B1-C1',
	'interfaces': [   {   'hw-id': '00:50:56:b9:76:04',
						  'ip': '10.1.2.1/24',
						  'name': 'eth1',
						  'vlan': '?'},
					  {   'hw-id': '00:50:56:b9:08:68',
						  'ip': '50.1.1.1/16',
						  'name': 'eth2',
						  'vlan': '?'},
					  {   'hw-id': '00:50:56:b9:16:85',
						  'ip': '10.1.50.1/24',
						  'name': 'eth3',
						  'vlan': '?'},
					  {   'hw-id': '00:50:56:b9:4e:c7',
						  'ip': '10.1.1.1/24',
						  'name': 'eth0',
						  'vlan': '?'}],
	'configure': {'netflow': '?', 'ospf': '?'}}]

Theese programs give output like this:

[
	{
		'name': '?',
		'path': '?',
		'hostname': 'B1-C1',
		'interfaces': [
			{
				'hw-id': '00:50:56:b9:76:04',
				'ip': '10.1.2.1/24',
				'name': 'eth1',
				'vlan': '?'
			},
			{
				'hw-id': '00:50:56:b9:08:68',
				'ip': '50.1.1.1/16',
				'name': 'eth2',
				'vlan': '?'
			},
			{
				'hw-id': '00:50:56:b9:16:85',
				'ip': '10.1.50.1/24',
				'name': 'eth3',
				'vlan': '?'
			},
			{
				'hw-id': '00:50:56:b9:4e:c7',
				'ip': '10.1.1.1/24',
				'name': 'eth0',
				'vlan': '?'
			}
		],
		'configure': {
			'netflow': '?',
			'ospf': '?'
		}
	}
]
