Upload Excel to Google Sheets automatically with Google Apps Script! In this complete step-by-step tutorial, you'll learn how to build a professional Excel-to-Google-Sheets automation system that lets users select an Excel file, upload it through a web app, process the Excel data, and automatically import it into Google Sheets.

Instead of manually opening Excel, copying rows, and pasting them into Google Sheets, we'll automate the entire workflow using Google Apps Script, Google Sheets, HTML, JavaScript, and the XLSX library.

By the end of this tutorial, you'll have a working Excel upload and import system that can be used as the foundation for real-world business applications.
