# How to Change Positive Numbers to Negative in Excel Shortcut: Quick Guide

Learning how to change positive numbers to negative in Excel can be a real lifesaver, especially if you’re dealing with large sets of data. By using a simple formula, you can quickly turn all positive numbers in a selected range into negative ones. Here’s a quick overview: you’ll use a formula to multiply each number by -1, and then copy and paste the new values back into your spreadsheet.

## How to Change Positive Numbers to Negative in Excel Shortcut

In this section, we’ll walk you through the steps to change positive numbers to negative in Excel using a shortcut. These steps will help you efficiently convert your numbers without any hassle.

### Step 1: Open Your Excel Worksheet

First, open the Excel worksheet that contains the positive numbers you want to convert.

Make sure that the data you want to change is visible and easily selectable. This will make the entire process smoother.

### Step 2: Select the Range of Numbers

Next, select the range of positive numbers you want to change to negative.

You can do this by clicking and dragging your mouse over the cells, or by holding down the Shift key while using the arrow keys.

### Step 3: Copy the Selected Cells

Now, copy the selected cells by pressing Ctrl+C on your keyboard.

### Step 4: Open a New Column or Area

Move to an empty column or area in your worksheet where you will paste and manipulate the copied data.

This step helps in keeping your original data intact while you work on converting the numbers.

### Step 5: Paste Special as Values

With the new column selected, right-click and choose "Paste Special," then select "Values."

This will paste only the values of your numbers into the new column, without any of the original formulas.

### Step 6: Apply the Formula to Change Signs

In the first cell of the new column, enter the formula =-1 (original cell reference). For example, =-1A1.

This formula will multiply the original number by -1, converting positive numbers to negative. Drag the fill handle to apply this formula to the rest of the cells in the new column.

### Step 7: Copy and Paste Back as Values

Finally, copy the newly changed cells and paste them back into the original cells as values.

This will replace the positive numbers with their negative counterparts in your original dataset.

After completing these steps, all the positive numbers in the selected range should now be negative. This process ensures that your data is accurately converted without any errors.

## Tips for Changing Positive Numbers to Negative in Excel Shortcut

1. Use Keyboard Shortcuts: Mastering keyboard shortcuts like Ctrl+C, Ctrl+V, and Ctrl+Shift+V can save you a lot of time.
2. Double-check Your Formulas: Always double-check the cell references in your formulas to ensure accuracy.
3. Backup Your Data: Before making bulk changes, it’s always a good idea to back up your data to prevent any accidental loss.
4. Use Paste Special Efficiently: The "Paste Special" feature is versatile, allowing you to paste values, formats, or even transpose data.
5. Practice Makes Perfect: The more you practice these steps, the more comfortable you’ll become with making these changes quickly and efficiently.

### How can I ensure my original data is not lost?

Make a copy of your worksheet or data range before making any changes. This way, you can always revert back if something goes wrong.

### Can I use this method for both rows and columns?

Yes, this method works for both rows and columns. Just ensure you select the correct range and update the cell references in your formulas.

### What if I have a mixed range with both positive and negative numbers?

The formula = -1*A1 will still work. It will also convert negative numbers to positive, so use this method only if you want all numbers reversed.

### Is there a faster way to do this with VBA?

Yes, VBA scripts can automate this process and handle large datasets more efficiently. However, it requires some basic programming knowledge.

### Can I undo the changes after applying the formula?

Yes, you can use the Undo button (Ctrl+Z) immediately after making the changes. For a more permanent backup, save your worksheet before starting the process.
