# json2csv

Convert JSON data to CSV data easily

# Usage

`json2csv` is a simple filter reading from standard input and sending to standard output.

```

$ json2csv outputfile

```

Usage of json2csv:

`-dedupe`

Remove duplicate rows. Usage: -dedupe=false (default true)

`-index` string

List index column name part. (default "#")

`-list` string

List column name part. (default "LIST")

`-separator` string

column name internal separator. (default ".")

# Description

`json2csv` works for JSON files which are already organized into simple record structures.

```JSON

[

  { "Title": "The Life of Brian",

    "date": { "year": "1908", "month": "January"},

    "cast" : [ "Joanna Lumley", "Terrance Trent Darby" ]

  },

  { "Title": "The Life of Pi",

    "date": { "year": "2012", "month": "January"},

    "cast" : ["Suraj Sharma", "Nota Tiger" ]

  }

]

```

The map keys are expected to become column names (not values), the map values are 

mapped to cells. Nested maps result in compound column names. Embedded lists have a 

row per each item in the list. The above is output as:

```

LIST,LIST.#,LIST.Title,LIST.date.year,LIST.cast.LIST,LIST.date.month,LIST.cast.LIST.#

,1,The Life of Brian,1908,Joanna Lumley,January,1

,1,The Life of Brian,1908,Terrance Trent Darby,January,2

,2,The Life of Pi,2012,Suraj Sharma,January,1

,2,The Life of Pi,2012,Nota Tiger,January,2

```

Here's the pretty version:

|LIST|LIST.#|LIST.Title       |LIST.date.year|LIST.cast.LIST      |LIST.date.month|LIST.cast.LIST.#|

|----|------|-----------------|--------------|--------------------|---------------|----------------|

|    |1     |The Life of Brian|1908          |Joanna Lumley       |January        |1               |

|    |1     |The Life of Brian|1908          |Terrance Trent Darby|January        |2               |

|    |2     |The Life of Pi   |2012          |Suraj Sharma        |January        |1               |

|    |2     |The Life of Pi   |2012          |Nota Tiger          |January        |2               |

# Column names

The column names format can be altered to avoid issues by using the command-line options. 

Example:

```

$ ./json2csv -list 'items' -index number -separator '_'
