Does gsutil cli tool support JSON output?

gsutil produces stdout output in it's custom key-value format which is quite inconvenient to parse. Is it possible to make gsutil generate JSON instead e.g. for this command:

gsutil ls -L gs://bucket-name/relative/path
gsutil bash

It appears as though replacing tabs with spaces is sufficient for pyyaml library to parse the output:

import re, subprocess, yaml

output = subprocess.check_output('gsutil ls -Lb gs://some-bucket-name'.split()).decode('utf-8')
bucket = yaml.safe_load(re.sub('\t', ' ', output))

The output will be in something that is closer to be yaml format. as mentioned in the code on the official GitHub repository and as part of gsutil the output format cannot be modified.

the output will be something like:

 gs://bucket/ :
            Storage class:                STANDARD
            Location constraint:          US
            Versioning enabled:           False

            Lifecycle configuration:      None
            Requester Pays enabled:       True
            Labels:                       None
            Default KMS key:              None

            ACL:
              [
                {
                  "entity": "project-owners-867489160491",
                  "projectTeam": {
                    "projectNumber": "867489160491",
                    "team": "owners"
                  },
                  "role": "OWNER"
                }
              ]
            Default ACL:
              [
                {
                  "entity": "project-owners-867489160491",
                  "projectTeam": {
                    "projectNumber": "867489160491",
                    "team": "owners"
                  },
                  "role": "OWNER"
                }
              ]

To get this as JSON i found this go repository that can work for encode the output as a JSON

git clone https://github.com/fedir/json_encode.git
cd json_encode
go build

gsutil ls -L gs://bucket-name  | ./json_encode
