COSCUP 2026 開源人年會

You already use Word and Excel every day. Turns out, those familiar tools share more with programming than you'd expect.This workshop starts exactly where you are — no coding background needed. We'll walk through how spreadsheet thinking connects to JavaScript, how document layout connects to HTML and CSS, and how a simple interactive button opens the door to modern web frameworks.Everything runs live in the browser. You'll see it, click it, and change it yourself.
