here's what I'm twerking' with

fix_json.js

// Goal is to convert the JSON at this URL into a json string that has the keys quoted
// https://wiki.cac.washington.edu/display/SWS/Term+Resource+V5+Sample+Resource

var fs   = require("fs");
var path = require("path");

var file = path.join(__dirname, "term_current.json");

var data = fs.readFileSync(file, "utf8");

//var scrubbed = data.replace(/^(.*?):/g, '"$&":$\' ');

var scrubbed = data.replace(/(['"])?([a-zA-Z0-9_]+)(['"])?:/g, '"$&"');
console.log(scrubbed);

data2 = JSON.parse(scrubbed);

console.log(JSON.stringify(data2));

output
