What Is Microsoft Excel and What Is It Used For

What You Will Learn and What You Will Need to Get Started with Microsoft Excel

Over 750 million people use Microsoft Excel. That number sounds impressive until you realize how many of them, whether in offices, classrooms, or job interviews, quietly panic when asked to do something beyond typing text into a cell. If you are starting from zero and want to actually understand what Microsoft Excel is and what it does, this is the article I wish had existed when I was the person sitting alone at a library computer with no one to ask.

By the end of this guide, you will be able to open Excel, make sense of what you are looking at, and understand which tasks it is actually built for. No prior experience is needed. You just need access to Microsoft 365 or the free Excel web app at Office.com.

Step 1: Understand What Microsoft Excel Actually Is (and Why It Still Matters in 2026)

Excel is spreadsheet software made by Microsoft. That is the technical answer. The more useful answer is that it is a grid, with rows running left to right and columns running top to bottom, where every intersection is a cell. Each cell can hold a number, a label, a date, or a formula that calculates something automatically.

I have used Excel daily since 2017 as a data analyst at a healthcare company in the Twin Cities. Most of what I do is clean up data exports, build reports, and create dashboards that department heads can actually read. Excel handles all of it. It is not glamorous, but it works reliably, and the skill transfers to almost every industry I have seen.

Rows, columns, cells, and workbooks: the four building blocks

A workbook is the file, the thing you save and email. Inside it are one or more worksheets, the individual tabs at the bottom. Each worksheet is built from rows (numbered 1, 2, 3, and so on) and columns (labeled A, B, C, and so on). Where they cross is a cell. Cell B3 means column B, row 3. That is the whole structure. Everything else, including formulas, charts, and pivot tables, sits on top of that grid. If you want a deeper look at how workbooks and worksheets relate to each other, the Excel workbooks and worksheets deep dive covers it thoroughly.

One thing worth knowing in 2026: Excel is not the same product it was five years ago. Excel Copilot, Microsoft's AI layer, can now write formulas for you, summarize data, and suggest charts based on what it sees in your sheet. For advanced users, Python in Excel (available to Microsoft 365 Business and Enterprise subscribers) lets you run Python code directly inside a spreadsheet. You do not need either of those on day one, but they are real, they are here, and they are why the "Excel is outdated" argument does not hold up.

Step 2: See What You Can Actually Do with Microsoft Excel

Now that you know what the grid is, the natural question is what to put in it. The answer depends entirely on where you are in the learning curve, so I will split this into two honest tiers.

Everyday tasks: budgets, lists, and simple tracking

On day one, you can build a personal budget, a grocery list with running totals, a workout log, or a coffee shop inventory tracker. These do not require formulas beyond basic addition. They just require you to type into cells and use a few columns to organize your thinking. That is a genuinely useful skill, and it is where I would suggest starting, with a real project rather than a tutorial exercise.

When I trained a new hire named Priya, a master's degree holder who had never used Excel beyond basic data entry, I skipped the documentation entirely and built an example from real data she would actually touch. Forty-five minutes later, she said:

This is the first time this has made sense.

The lesson was not about Excel. It was about starting with something real.

Power tasks: data analysis, pivot tables, and formulas

Once you are past the basics, formulas and functions are where Excel earns its reputation. SUM adds numbers. VLOOKUP finds data across sheets. IF tests a condition and returns different results depending on the answer. These are not exotic; they show up in nearly every professional spreadsheet. Our Excel basics for beginners advanced guide walks through these in plain language if you want a structured path.

Pivot tables are the feature most beginners avoid and most hiring managers test. They let you summarize thousands of rows into a readable table in about thirty seconds. I have seen it come up in more than a dozen hiring processes over the years. Candidates who cannot do it remember that moment for a long time. For data analysis, Excel also has Power Query, a tool for cleaning and reshaping data imports that is significantly underused outside of finance and analytics roles.

Step 3: Know When to Use Excel vs. Google Sheets (Common Beginner Mistake)

With the basics in view, there is a decision beginners almost always skip, and it causes real confusion later. Excel and Google Sheets do similar things, but they are not interchangeable.

Google Sheets is a better starting point than Excel for many students, and I will say that on an Excel blog without apology, because it is true. If you are sharing files constantly, working on a Chromebook, or just want something free right now, start there. If your job or school requires Excel specifically, or you are heading toward data-heavy work, learn Excel. The core logic transfers either way.

On cost: Excel is not free in its full desktop form. A Microsoft 365 Personal subscription runs around $70 per year. The browser-based version at Office.com is free and handles most beginner tasks, but some features, including Copilot and Python in Excel, require a paid plan.

Next Steps: Where to Go After You Understand What Excel Is

A semester of serious Excel instruction would do more for most college graduates' employability than a full elective in business theory. I believe that. The gap between "I know Excel" on a resume and actually knowing it is one of the quieter career problems in white-collar work.

The best next step is not a course. It is a real project. Build a budget for last month. Track something you already care about. Open a blank workbook and type something in. From there, the Excel for beginners complete starter guide gives you a structured path through the fundamentals without the usual hand-waving.

Excel in 2026 is a different product than the one your parents learned. Copilot writes formulas on request. Python runs inside cells. Power Query handles data cleanup that used to require hours of manual work. You do not need any of that today, but it is worth knowing the ceiling is a lot higher than it looks from the ground floor.
