HTML table data to JSON

suckData.js

/*
 * THIS IS NOT A PLUGIN
 *  ~ but a personal snippet
 *
 * Sometimes when prototyping my designs, I like to get dummy data pretty fast.
 * I use this snippet to extract that data from working (aka "real life") tables from other HTML tables I find on the net.
 * So I'll need that same data but inside an object.
 * 
 * This script assumes by default the table has the following structure:
 * <table>
 *  <thead>
 *    <tr><th>
 *  <tbody>
 *    <tr><td>

var o = { // default options
      selectors: {
        table: 'table',
        th: 'thead th', // relative to $table
        tr: 'tbody tr' // relative to $table
      }
    },
    $table,
    data = [],
    headings = [],
    log = console.log;

$table = document.querySelector(o.selectors.table);

// Get headings
$table.querySelectorAll(o.selectors.th).forEach((th) => {
  headings[headings.length] = th.innerText;
});

$table.querySelectorAll(o.selectors.tr).forEach((tr, row) => {
    var obj = data[row] = {};
    tr.querySelectorAll('td').forEach((td, i) => {
        obj[headings[i]] = td.innerText;
    })
});

log(JSON.stringify(data));
