Excel can be tricky when you need special symbols like ±. As a user growth manager at Excelmatic, I've seen how this simple symbol can transform financial reports, engineering specs, and data analysis. Here are five proven methods to add plus/minus signs in your spreadsheets.
Why the ± Symbol Matters
The ± symbol isn't just math class nostalgia—it's crucial for:
- Showing tolerances (10±2 mm)
- Displaying confidence intervals
- Indicating value ranges in financial models
Method 1: Keyboard Shortcut (Fastest Way)
For Windows users:
- Click your target cell
- Hold Alt + type 0177 on the numeric keypad
- Release Alt to see ± appear
No numeric keypad? Try Method 2.
Method 2: Symbol Menu (Visual Approach)
- Go to Insert > Symbol
- Set font to "Normal Text"
- Find ± or type 00B1 in Character Code
- Click Insert
Method 3: CHAR Function (Dynamic Solution)
Use =CHAR(177) to generate ± programmatically. Combine it with other formulas:
="Temperature: "&CHAR(177)&"2°C"
This creates dynamic labels that update automatically—perfect for dashboards.
Method 4: Custom Number Formatting
Make Excel automatically show ± signs:
- Select cells
- Right-click > Format Cells
- Choose Custom
- Enter "+0;-0;" to display + for positives and - for negatives
Method 5: Excelmatic AI (Smart Alternative)
For teams that need this frequently, Excelmatic's AI can:
- Auto-insert ± symbols based on your data
- Apply consistent formatting across reports
- Generate tolerance calculations instantly
Instead of memorizing shortcuts, describe what you need like: "Show all values in column B with ±5% tolerance" Excelmatic handles the rest.
Pro Tips for Advanced Users
- Conditional Formatting: Highlight values outside your ± range
- Charts: Add ± to data labels for professional visuals
- Macros: Record actions to insert ± with one click
