October 17 marks a quiet revolution. On this day in 1979, VisiCalc shipped—the first electronic spreadsheet—and suddenly, anyone with a computer could model ideas, track budgets, and make decisions faster than ever before. That simple grid of rows and columns became the backbone of modern business, education, and creativity.
How Did Spreadsheet Day Begin?
Spreadsheet Day was created in 2010 by Excel MVP Debra Dalgleish, known worldwide for her work at Contextures. Her goal was simple: celebrate the spreadsheet’s impact and the vibrant community around it. She chose October 17 to honor VisiCalc’s release—the moment spreadsheets went digital and changed everything.
A Quick Look Back
Before spreadsheets, recalculating a budget meant erasing and rewriting by hand. VisiCalc changed that overnight, and Excel carried the torch—bringing charts, formulas, and collaboration to millions. Over four decades, spreadsheets have evolved from static tables to dynamic engines for analysis and storytelling. They’ve powered breakthroughs in science, finance, and even art.
Beyond the features, spreadsheets represent something bigger: empowerment. They give anyone the ability to turn raw data into insight. That’s why Spreadsheet Day isn’t just about software—it’s about the people who use it to solve problems every day.
Debra’s vision sparked a tradition that now spans the globe. Educators, analysts, and enthusiasts join in each year to share tips, stories, and appreciation for a tool that empowers millions—a reminder that community matters as much as technology.
Meet the Spreadsheet Champions
Celebrate Spreadsheet Day with a sneak peek at Spreadsheet Champions, a documentary that goes beyond formulas to tell a human story.
This film follows six students from around the world as they compete in Microsoft’s Excel challenge. Each brings unique hopes and struggles—whether it’s De La Paix in Cameroon aiming to make his family proud, Carmina in Guatemala finding refuge in math, or Mason in the U.S. balancing his love for spreadsheets with quirky hobbies. Alongside Alkmini from Greece, Nam from Vietnam, and Braydon from Australia, these young competitors reveal how mastering a spreadsheet can unlock confidence, opportunity, and even friendship.
It’s a celebration of resilience, creativity, and the influence of spreadsheets in shaping lives today.

Why We Celebrate
Spreadsheet Day isn’t about nostalgia—it’s about recognizing the creativity and problem‑solving that spreadsheets unlock. Every chart that clarifies a decision, every formula that saves a late night, every model that helps a team plan better—that’s the legacy we’re celebrating.
Today, spreadsheets are everywhere: in classrooms, boardrooms, and even living rooms. They’ve helped launch companies, plan weddings, analyze sports stats, and map out personal goals. Spreadsheet Day is our chance to pause and appreciate the tool that makes all of that possible.
