bajson

library for converting to/from json

Install

 $ pip install bajson

Usage

JSON to CSV

• the root of the input json should be in list format

  Invalid

  "data": [
      {
        "data": "value",
        "data1": "value1"
      },
      {
        "data": "value2",
        "data1": "value3"
      },
    ]

  Valid

  [
    {
      "data": "value",
      "data1": "value1"
    },
    {
      "data": "value2",
      "data1": "value3"
    },
  ]

• Converting nested json objects

  [
    {
      "data": {
            "firstkey": "firstvalue",
            "secondvalue": "secondvalue",
          },           
      "data1": "value1"
    },
    {
      "data": {
            "firstkey": "firstvalue1",
            "secondvalue": "secondvalue1",
          },           
      "data1": "value2"
    },
  ]

  data.firstkey	data.secondkey	data1
  firstvalue	secondvalue	value1
  firstvalue1	secondvalue1	value2

• Converting arrays in json objects

  [
    {
      "data": [
            "firstvalue",
            "secondvalue",
          ],           
      "data1": "value1"
    },
    {
      "data": [
            "firstvalue1",
          ],           
      "data1": "value2"
    },
  ]

  data.0	data.1	data1
  firstvalue	secondvalue	value1
  firstvalue1		value2

Code Example

from bajson.libcsv import json_to_csv

json_to_csv("input.json", "output.csv")

CSV to JSON

bajson can convert csv file to json format vice versa. Formats above are valid for this operation too. However there is one exception about array conversion,

If csv headers are as follows

data.0	data.1	data1
firstvalue	secondvalue	value1
firstvalue1		value2

This will be converted to object form instead of array form (it can be added in future release)

[
  {
    "data": {
          "0": "firstvalue",
          "1": "secondvalue",
        },           
    "data1": "value1"
  },
  {
    "data": {
          "0": "firstvalue1",
        },           
    "data1": "value2"
  },
]

Code Example

from bajson.libcsv import csv_to_json

csv_to_json("input.csv", "output.json")

Future features

• Support string input/output parameters
• JSON <==> XML
