Converting Positive Numbers to Negative in Excel on Windows 11: A Guide

Have you ever been in a situation where you needed to convert a bunch of positive numbers to negative in Excel? Well, you’re in luck! It’s actually a pretty simple process. In this article, we’ll go over how to do just that in Windows 11. By the end, you’ll be a pro at flipping those numbers around with ease.

Step by Step Tutorial: Converting Positive Numbers to Negative in Excel

Before we dive into the steps, let’s quickly go over what we’ll be doing. We’ll be using a formula in Excel that multiplies your positive numbers by -1, turning them into negative numbers. It’s a quick and easy way to get the job done.

Step 1: Open your Excel spreadsheet

Open the Excel spreadsheet that contains the positive numbers you want to convert to negative.

This step is pretty straightforward. Just open up Excel and find the spreadsheet with the numbers you need to convert.

Step 2: Select the cells with positive numbers

Click and drag to highlight all the cells with the positive numbers you want to convert.

Make sure you’ve got all the cells selected that you want to change. You don’t want to miss any!

Step 3: Type the formula

Type the formula =A1*-1 into an empty cell, where A1 is the first cell you want to convert.

This formula is what will do the magic. It multiplies the number in the cell by -1, flipping it to a negative.

Step 4: Press Enter

After typing the formula, press Enter to apply it.

Once you hit Enter, you’ll see the number in the cell change from positive to negative.

Step 5: Drag the fill handle

Click and drag the fill handle (the small square at the bottom right of the cell) down or across to apply the formula to all selected cells.

Dragging the fill handle will copy the formula to all the other cells you’ve selected, converting all the numbers to negative.

After you’ve completed these steps, you’ll have successfully converted all your positive numbers to negative. It’s a quick and easy process that can save you a lot of time if you’re working with a lot of data in Excel.

Tips: Converting Positive Numbers to Negative in Excel

  • Make sure you’re using the correct cell reference in the formula. If you’re converting a different cell than A1, you’ll need to adjust the formula accordingly.
  • If you have a lot of numbers to convert, it might be easier to use the “Paste Special” feature to multiply all selected cells by -1 in one go.
  • Remember that this method will not work if the cells you’re converting contain formulas. You’ll need to copy and paste the values first before applying the negative multiplier.
  • If you accidentally convert a number you didn’t mean to, you can easily undo the action by pressing Ctrl + Z.
  • Keep in mind that converting a number to negative does not change its absolute value, just the sign. Be sure this is the result you want before applying the formula.

Frequently Asked Questions

What if I need to convert negative numbers to positive?

You can use the same process, but instead of multiplying by -1, you would multiply by 1, or simply use the ABS function in Excel which returns the absolute value of a number.

Can I convert multiple numbers at once?

Yes, you can convert multiple numbers at the same time by dragging the fill handle across all the cells you want to convert after entering the formula.

What happens if I apply the formula to a cell that is already negative?

The number will become positive, as multiplying a negative number by -1 will flip the sign to positive.

Can I use this method on numbers with decimals?

Absolutely, this method works on any numerical value, whether it’s a whole number or a decimal.

Is there a shortcut to apply the formula to all selected cells?

Yes, after typing the formula, you can press Ctrl + Enter to fill all selected cells with the formula at once.


  1. Open your Excel spreadsheet.
  2. Select the cells with positive numbers.
  3. Type the formula =A1*-1.
  4. Press Enter.
  5. Drag the fill handle to apply the formula to all cells.


Converting positive numbers to negative in Excel on Windows 11 is a piece of cake once you know how to do it. With the simple formula =A1*-1, you can quickly flip the sign of as many numbers as you need. Whether you’re working with a small set of data or a large spreadsheet, this method will save you time and ensure accuracy in your calculations. Don’t let the sign of a number slow you down. Give this method a try and watch those positives turn into negatives with ease. And remember, if you ever need to do the reverse and turn negatives into positives, the same process applies, just with a positive multiplier. Happy number crunching!
