Korshub's take

Turning a Google Sheet into a live JSON API

This course shows how to use Google Apps Script and JavaScript to output the contents of a Google Sheet as JSON and expose it through a web app, so a website can fetch that data directly. It's explicitly not for absolute beginners — some prior coding experience is expected before starting.

What you'll build

A spreadsheet-backed JSON endpoint using the Apps Script doGet() method
Dynamic JSON structured from the sheet's own header row
A page that fetches and displays that JSON data with JavaScript Fetch
Interactive buttons that POST data back from a webpage into the sheet using doPost()

Debugging and troubleshooting

The course also covers using the Apps Script IDE to debug, working with the Fetch and formData methods, resolving common CORS issues with Apps Script web apps, and using Logger to trace values during development.

It's taught by a Google Developer Expert, giving the material direct grounding in the platform's own tooling.
