json-dotenv is a free and open-source, we develop it to manipulate and extract envfiles in json format.
pip install json-dotenv
usage: json-dotenv [-h] [--allow-envvar] [-c {list,keys,get,set,unset}]
[-k KEY] [-v VALUE] [-f FILE] [--force]
[-l {critical,error,warning,info,debug}]
[--logfile LOGFILE] [-o OUTPUT] [-q {always,never,auto}]
[--format {env,json}]
[{list,keys,get,set,unset}]
positional arguments:
{list,keys,get,set,unset}
Commands: list, keys, get, set, unset
optional arguments:
-h, --help show this help message and exit
--allow-envvar Allow environment variables expansion, instead of
False
-c {list,keys,get,set,unset}
Commands: list, keys, get, set, unset, instead of list
(deprecated)
-k KEY, --key KEY variable name to set or unset
-v VALUE, --value VALUE
variable value to set
-f FILE Location of the environment file or from stdin (-),
instead of .env
--force Force the output even if there is an error
-l {critical,error,warning,info,debug}, --loglevel {critical,error,warning,info,debug}
Emit traces with LOGLEVEL details, must be one of:
critical, error, warning, info, debug
--logfile LOGFILE Use log file <logfile> instead of /var/log/json-dotenv
/json-dotenv.log
-o OUTPUT Output result in file or to stdout
-q {always,never,auto}
Whether to quote or not the variable values, instead
of always. This does not affect parsing
--format {env,json} Output format env or json, instead of json
List all environment variables in file foo.env:
json-dotenv list -f foo.env
