json2yaml

Command line utilities to convert between JSON and YAML while preserving the order of associative arrays.

Preserving the mapping order is helpful to humans reading the documents, despite not affecting their meaning.

Install

pip install json2yaml

Usage

json2yaml input.json output.yaml

yaml2json input.yaml output.json

$ json2yaml --help
Usage:
    json2yaml (--version|--help)
    json2yaml [<json_file>] [<yaml_file>]

Arguments:
    <json_file>    The input file containing the JSON to convert. If not
                   specified, reads from stdin.
    <yaml_file>    The output file to which to write the converted YAML. If
                   not specified, writes to stdout.
$ yaml2json --help
Usage:
    yaml2json (--version|--help)
    yaml2json [-i <indent>] [<yaml_file>] [<json_file>]

Arguments:
    -i, --indent=INDENT  Number of spaces to indent [default: 4]
    <yaml_file>          The input file containing the YAML to convert. If not
                         specified, reads from stdin.
    <json_file>          The output file to which to write the converted JSON.
                         If not specified, writes to stdout.
