🎉 Forty years of Excel: innovation, community, and celebration 🎉
This year marks a major milestone—Microsoft Excel turns 40! In honor of four decades of innovation, we’re kicking off “40 Days of Excel”, a global community celebration spotlighting the features that made Excel iconic.
It all started on September 30, 1985, when Excel debuted on the Macintosh, introducing a revolutionary graphical interface for spreadsheets. Since then, Excel has evolved into a productivity powerhouse, empowering people and organizations across the globe.
Starting today, August 6, we’ll count down to Excel’s birthday with 40 days of features—each one introduced by an Excel MVP or Creator. These passionate experts will share what makes each feature special, offer pro tips, and tell personal stories of how Excel has shaped their work and creativity.
This isn’t just a look back—it’s a 40-day journey through Excel’s evolution, packed with nostalgia, insights, and surprises. We invite you to follow along, learn something new, and share your own Excel memories with us.
