A library for converting json to a table.

It uses https://github.com/zhiburt/tabled to build a table.

Usage

Add the library to a dependency list.

[dependencies]
json_to_table = "*"

The main and only function you shall use to build a table is json_to_table.

Example Result 
use json_to_table::json_to_table;
use serde_json::json;

fn main() {
    let value = json!(
        [
            {
                "name": "Aleix Melon",
                "id": "E00245",
                "role": ["Dev", "DBA"],
                "age": 23,
                "doj": "11-12-2019",
                "married": false,
                "address": {
                    "street": "32, Laham St.",
                    "city": "Innsbruck",
                    "country": "Austria"
                    },
                "referred-by": "E0012"
            },
        ]
    );

    let table = json_to_table(&value).to_string();

    println!("{}", table)
}

You can also build a table in a squash mode.

Example Result 
use json_to_table::json_to_table;
use serde_json::json;

fn main() {
    let value = json!(
        [
            {
                "name": "Aleix Melon",
                "id": "E00245",
                "role": ["Dev", "DBA"],
                "age": 23,
                "doj": "11-12-2019",
                "married": false,
                "address": {
                    "street": "32, Laham St.",
                    "city": "Innsbruck",
                    "country": "Austria"
                    },
                "referred-by": "E0012"
            },
        ]
    );

    let table = json_to_table(&value).collapse().to_string();

    println!("{}", table)
}

|             +---------+---------------+

You can chose how to build an Array and Object via Orientation.

Example Result 
use json_to_table::{json_to_table, Orientation};
use serde_json::json;

fn main() {
    let value = json!(
        [
            {
                "name": "Aleix Melon",
                "role": ["Dev", "DBA"],
                "age": 23,
                "referred-by": "E0012"
            },
            {
                "name": "Aleix Melon",
                "role": ["DBA"],
                "age": 24,
                "referred-by": "E0012"
            },
        ]
    );

    let table = json_to_table(&value)
        .set_object_mode(Orientation::Horizontal)
        .to_string();

    println!("{}", table)
}
