Install
npm install json-to-tableInfo
json-to-table converts an array of Javascript objects into a table format.
The column headers are all the possible "leaves" of the javascript objects.
Usage
const jsonToTable = require('json-to-table');
const myRecords = [
{
name:'Bob',
address:{zip:12345, state:'Euphoria'}
},
{
name:'Jon',
address:{street:'1234 Main St.', state:'Arizona'}
}];
const tabled = jsonToTable(myRecords);
//tabled will be an array of arrays like this
//[
//['name', 'address.zip', 'address.state', 'address.street'],
//['Bob', 12345, 'Euphoria', ''],
//['Jon', '', '1234 Main St.', 'Arizona']
//]Options
Some available options to pass in as the second argument are as follows.
Look at the tests to see all of these options in action.
{
defaultValue: put whatever you want here //defaults to an empty string
includeCollectionLength: if there is a subarray within the object, it will create a header and include that length //defaults to false
excludeSubArrays: if there is a subarray within the object, it will remove it completely from the resulting table. //defaults to false
checkKeyBeforePath: this will check for a key that has a '.' in it before assuming the '.' means to look deeper in the object //defaults to false
listSubArrays: if there is a subarray that does not contain objects, it will list the full array instead of breaking it up into individual columns. //defaults to false
stringifyObjects: stringify arrays and objects instead of breaking them up into individual columns // defaults to false
}Notes
If a particular object did not have a key that another one did, the default will be an empty string.
You can change the default value by passing an option in as the second parameter of the function call.
If you explicitly pass undefined in as the second value, your defaults will be undefined.
const jsonToTable = require('json-to-table');
const myRecords = [
{
name:'Bob',
address:{zip:12345, state:'Euphoria'}
},
{
name:'Jon',
address:{street:'1234 Main St.', state:'Arizona'}
}];
const tabled = jsonToTable(myRecords, 'MY_DEFAULT_STR!!');
//tabled will be an array of arrays like this
//[
//['name', 'address.zip', 'address.state', 'address.street'],
//['Bob', 12345, 'Euphoria', 'MY_DEFAULT_STR!!'],
//['Jon', 'MY_DEFAULT_STR!!','Arizona', '1234 Main St.']
//]Also note that in this example, the address.zip was a number, and stayed a number.
