Looks very much like the output of Core Lightning cli when used with flag -F:

```

$ lightning-cli -F listchannels |head

channels[0].source=02e4ebfc64bf742e100f7ed1f4f9c4f3ce03109face9cf5eab58529bd3a5fc6ce9

channels[0].destination=02ff30e83896d453cfc89ff4dd06d23d793b7246f154c210324adc1d42c849ce74

channels[0].short_channel_id=771657x2489x1

channels[0].direction=0

channels[0].public=true

channels[0].amount_msat=3000000000

channels[0].message_flags=1

channels[0].channel_flags=2

channels[0].active=false

channels[0].last_update=1701194704

```

Very useful
