fconv

fconv is a Command-Line utility and library for converting between multiple file formats such as JSON, YAML.

Getting started

pip install fconv

$ fconv --v
fconv: vx.x.x

Features

• Convert a format into other format

• Supported format

  • JSON
  • YAML
  • TOML
  • XML

• To be supported

  • INI
  • JSON5

• You can use fconv as command-line tool and Python module.

• Using fconv as a module, String and file are available as input or output.

• Using fconv as CLI tool, only file is available as input and String and file are available as output.

The options available in the CLI version are different from those available in the module version.

To know which options are available,

See SPEC.md:

Example

Use as a module

>>> from fconv.core import Former
>>> from fconv.formats.json import Json
>>> from fconv.formats.yaml import Yaml
>>> f = Former(src_format=Json, target_format=Yaml)

>>> f.form('{"key1":"value1"}')
'key1: value1\\n'

>>> f = Former(src_format=Yaml, target_format=Json, out_opt={'indent':3})
>>> f.form('key1: value1\\n')
'{\\n   "key1": "value1"\\n}'

Use as a command-line tool

Basic usage

fconv <source format> <target format> -i <source file name>

Convert json file into yaml and print out

fconv json yaml -i sample.json

Convert yaml file into json formated file

fconv yaml json -i sample.yaml -o result.json

Convert yaml file into json formated file with json indent option

fconv yaml json -i sample.yaml -o result.json --json-indent 2

$ fconv -h

Converter between multiple open-standard file formats.

positional arguments:
  source-format         data format converting from
  target-format         data format converting to

options:
  -h, --help            show this help message and exit
  -i I                  (Required) a file converting from
  --v                   print version number and exit
  --debug               print more information
  -o O                  a file converting to
  --json-float-as-int   JSON float to be decoded with int
  --json-float-as-str   JSON float to be decoded with string
  --json-int-as-float   JSON int to be decoded with float
  --json-int-as-str     JSON int to be decoded with string
  --json-skip-keys      keys that are not of a basic type (str, int, float,
                        bool, None) will be skipped
  --json-ignore-check-circular
                        the circular reference check for container types will
                        be skipped
  --json-disallow-nan   disallow to serialize out of range float values (nan,
                        inf, -inf) in strict compliance of the JSON
                        specification.
  --json-indent JSON_INDENT
                        JSON array elements and object members will be pretty-
                        printed with that indent level.
  --json-sort-keys      the output of dictionaries will be sorted by key.
  --yaml-explicit-start
                        add explicit start marker(See also
                        https://yaml.org/spec/1.2.2/#914-explicit-documents)
  --yaml-explicit-end   add explicit end marker(See also
                        https://yaml.org/spec/1.2.2/#914-explicit-documents)
  --yaml-indent YAML_INDENT
                        YAML array elements and object members will be pretty-
                        printed with that indent level.
  --xml-process-namespaces
                        enable namespace support(See more info at
                        https://github.com/martinblech/xmltodict#namespace-
