Convert object array:

[
    {
        "id": 1,
        "name": "foo",
        "favorites": {
            "fruits": "apple",
            "color": "red"
        }
    },
    {
        "id": 2,
        "name": "bar",
        "favorites": {
            "fruits": "orange"
        }
    },
    {
        "id": 3,
        "name": "baz",
        "favorites": {
            "fruits": "banana",
            "color": "yellow"
        }
    }
]

$ json2csv example1.json

/id,/name,/favorites/color,/favorites/fruits
1,foo,red,apple
2,bar,,orange
3,baz,yellow,banana

Convert object:

{
    "status": 200,
    "result": [
        {
            "id": 1,
            "name": "foo"
        },
        {
            "id": 2,
            "name": "bar"
        }
    ]
}

$ json2csv example2.json

/status,/result/0/id,/result/0/name,/result/1/id,/result/1/name
200,1,foo,2,bar

Convert an array of the object:

Use --path=<JSON Pointer> option.

$ json2csv --path=/result example2.json

/id,/name
1,foo
2,bar

Transpose rows and columns:

$ json2csv --transpose example1.json

/id,1,2,3
/name,foo,bar,baz
/favorites/color,red,,yellow
/favorites/fruits,apple,orange,banana

Header styles

By default, header is represented with JSON Pointer. --header-style=STYLE option can change styles.

style	example
jsonpointer	/foo/bar/0/baz
slash	foo/bar/0/baz
dot	foo.bar.0.baz
dot-bracket	foo.bar[0].baz

Note: slash style similar to jsonpointer style, but slash style doesn't start with '/' and doesn't escape special characters ('/' and '~') defined in RFC 6901.

Note: dot-bracket style similar to dot style, but dot-bracket style uses square brackets for array indexes.
