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
