Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Convert Google Spreadsheets to JSON using Javascript

Uses the google-spreadsheet library to fetch data.

The final JSON is based on sheets names and column titles and finally looks like this :

{
  "Customers": [
    {
      "name": "Sony",
      "country": "Japan"
    },
    {
      "name": "Renault",
      "country": "France"
    }
  ],
  "Invoices": [
    {
      "id": "F0001",
      "totalAmount": "12367.12"
    },
    {
      "id": "F0002",
      "totalAmount": "4398.2"
    }
  ]
}

This can be useful when you want people edit spreadsheets and need to work with the data.

Install

npm i --save spreadsheet-to-json

QuickStart

extractSheets can use node callback pattern or async/await.

const { extractSheets } = require("spreadsheet-to-json");

// optional custom format cell function
const formatCell = (sheetTitle, columnTitle, value) => value.toUpperCase();

extractSheets(
  {
    // your google spreadhsheet key
    spreadsheetKey: "abch54Ah75feBqKGiUjITgE9876Ypb0yE-abc",
    // your google oauth2 credentials or API_KEY
    credentials: require("./google-generated-creds.json"),
    // optional: names of the sheets you want to extract
    sheetsToExtract: ["Customers", "Invoices"],
    // optional: custom function to parse the cells
    formatCell: formatCell
  },
  function(err, data) {
    console.log("Customers: ", data.Customers);
    console.log("Invoices: ", data.Invoices);
  }
);

see ./example.js

Authentification

The credentials key can either be a API_KEY string or a service account object.

API Key

You can create an API key here : https://console.developers.google.com/apis/credentials

Be sure to restrict it to Google Drive API

Google service account

Create a credentials.json file for your app here : https://console.developers.google.com/

  • create a new project
  • enable the Drive API
  • in credentials, select create new credentials then service account and save the generated JSON. (privately)
  • then give the JSON contents to the credentials parameter in the extractSheets call.

Share the target google spreadsheet with the client_email from the credentials.json.
