How can I reformat JSON with awk?

Question

I have information as given below in a text file.

{"00:00:00:00:00:00:02:03":[{"controllerId":"onos-primary"}],"00:00:00:00:00:00:02:02":[{"controllerId":"onos-primary"}],"00:00:00:00:00:00:02:01":[{"controllerId":"onos-primary"}],"00:00:00:00:00:00:02:06":[{"controllerId":"onos-primary"}],"00:00:00:00:00:00:02:05":[{"controllerId":"onos-primary"}],"00:00:00:00:00:00:02:04":[{"controllerId":"onos-primary"}]}

I want that information to be like this.

{
"00:00:00:00:00:00:02:03":[{"controllerId":"onos-primary"}],
"00:00:00:00:00:00:02:02":[{"controllerId":"onos-primary"}],
"00:00:00:00:00:00:02:01":[{"controllerId":"onos-primary"}],
"00:00:00:00:00:00:02:06":[{"controllerId":"onos-primary"}],
"00:00:00:00:00:00:02:05":[{"controllerId":"onos-primary"}],
"00:00:00:00:00:00:02:04":[{"controllerId":"onos-primary"}]
}

How can I acheieve this using Linux commandline.? I am willing to use awk or sed or simple bash

You can use

awk '{sub('/^{/', "{\n", $0); sub('/}$/', "\n}", $0); gsub('/,/', ",\n", $0); print;}' filename

This might work for you (GNU sed):

sed -r 's/\{(.*)\}/{\n\1\n}/;s/,/&\n/g' file
