Open Excel and start with a blank spreadsheet

The fastest way to begin is to open Excel on your computer and select Blank workbook from the start screen. If Excel is already open, go to File in the top left, then New, then Blank workbook. You will see a grid of empty cells — that is your spreadsheet, ready to use.

Each cell is named by its column letter and row number. The cell in the top left corner is A1. The cell to its right is B1. The cell below A1 is A2. This naming system matters because you will use it later to write formulas that do math or pull information from other cells.

Key Takeaways

  • Start with a blank workbook, then click on a cell and type your headers — the labels that describe what each column contains.
  • Enter your data row by row, with one piece of information per cell, so Excel can sort and filter it later.
  • Use formulas like =SUM() to add numbers or =AVERAGE() to find the middle value, and Excel will update the answer automatically when your data changes.
  • Save your file with a clear name that tells you what it contains, and use the .xlsx format so you can open it on any device.
  • Format your spreadsheet by making headers bold, widening columns so text is readable, and freezing the top row so it stays visible when you scroll down.

Add headers and organize your columns

Click on cell A1 and type a label for your first column. If you are tracking household expenses, you might type Date. Press Tab to move to B1 and type the next header — perhaps Category. Keep pressing Tab and typing until you have labeled all your columns. These headers tell you and anyone else reading the spreadsheet what information belongs in each column.

Headers should be specific enough to be clear but short enough to fit in the column without taking up too much space. Amount Spent is better than How Much Money Did We Use. Once your headers are in place, click on the row number 1 on the left side to select the entire first row, then click the Bold button in the toolbar. This makes your headers stand out from your data.

Enter your data one row at a time

Click on cell A2 (the first cell below your headers) and start typing your information. For a household budget, you might type today's date. Press Tab to move to the next cell and type the category — groceries, utilities, or whatever applies. Keep pressing Tab and entering information until you reach the end of that row.

When you press Enter at the end of a row, Excel moves you down to the next row and back to the first column. This rhythm — Tab to move right, Enter to move down — is faster than clicking each cell. Enter your data this way until you have recorded everything you need. The more organized your data is now, the easier it will be to sort, filter, or calculate with it later.

Use formulas to calculate totals and summaries

Once your data is entered, you can use formulas to do math automatically. Click on an empty cell below your data — for example, if your numbers are in cells A2 through A10, click on A11. Type =SUM(A2:A10) and press Enter. Excel will add all the numbers in that range and show you the total. The colon between A2 and A10 means "from A2 to A10".

Other common formulas include =AVERAGE(A2:A10) to find the middle value, =COUNT(A2:A10) to count how many cells have numbers in them, and =MAX(A2:A10) to find the largest number. If you change any of the numbers in your data, the formula updates automatically — you do not have to recalculate by hand. This is one of the main reasons to use a spreadsheet instead of writing numbers on paper.

Widen columns and freeze headers so the spreadsheet is readable

If your text is cut off or hard to read, widen the column. Move your cursor to the line between two column letters at the top — for example, between the A and B — until the cursor changes to a resize arrow. Then click and drag to the right to make the column wider. Do this for any column where text is hidden or cramped.

If you have many rows of data, freeze the header row so it stays visible when you scroll down. Click on cell A2 (the first cell below your headers), then go to the View tab at the top and click Freeze Panes. Now when you scroll down through your data, row 1 will stay at the top of the screen. This keeps you from losing track of what each column means.

Save your spreadsheet with a clear filename

Go to File and click Save As. Choose where you want to save the file — your Documents folder is a common choice. Type a filename that describes what the spreadsheet contains, like Household Budget 2024 or Garden Planting Schedule. Make sure the file format is set to .xlsx, which is the standard Excel format and works on Windows, Mac, and other devices.

Save your file regularly as you work — press Ctrl+S on Windows or Command+S on Mac to save quickly without opening the menu. If you need to share the spreadsheet with someone else, .xlsx format ensures they can open it no matter what device they use.

Frequently Asked Questions

What is the difference between a column and a row?

Columns run vertically from top to bottom and are labeled with letters (A, B, C). Rows run horizontally from left to right and are labeled with numbers (1, 2, 3). A cell is where a column and row meet — cell B3 is in column B, row 3.

Can I sort my data after I enter it?

Yes. Click on any cell in your data, then go to the Data tab and click Sort. Excel will ask which column you want to sort by — for example, you can sort expenses from smallest to largest, or dates from oldest to newest. Your entire rows move together so the data stays matched up.

What happens if I type a formula wrong?

Excel will show an error message like #NAME? or #VALUE!. Click on the cell with the error and look at the formula bar at the top — it shows exactly what you typed. Check that you spelled the function correctly (SUM, not SUMS) and that your cell range is right (A2:A10, not A2-A10).

Can I use Excel on my phone or tablet?

Yes. Microsoft offers free Excel apps for iPhone, iPad, and Android. You can view and edit spreadsheets you have saved to OneDrive or SharePoint. The mobile version has fewer features than the desktop version, but it works for basic data entry and viewing.

How do I add a new row in the middle of my data?

Right-click on the row number where you want to insert a new row, then click Insert. A blank row appears, and all the rows below it shift down. This keeps your data organized without losing anything.
