How do I parse text into a JSON object?

I have a dhcp lease file with the following example entries:

lease 172.16.20.11 { starts 4 2014/10/09 18:33:57; ends 4 2014/10/09 18:43:57; cltt 4 2014/10/09 18:33:57; binding state active; next binding state free; rewind binding state free; hardware ethernet XX:XX:XX:XX:XX:XX; client-hostname "phone"; }

I am trying to find a way to convert the information into JSON so I can use in Dojo.

I would like the output to be like

{"leases": ["address":"172.16.20.11", "starts":"2014/10/09 18:33:57", "ends":"2014/10/09 18:43:57","
client-hostname":"phone"]}

Is there a way to do this?

Thanks, Tim T
