Question details
The user needs a solution for matching parentheses no longer turning bold while editing formulas in Excel.

- Product
- Microsoft Excel (Office 2021)
- Device & OS
- Windows 11
- Scenario
- Editing and troubleshooting complex spreadsheet formulas where identifying matching sets of parentheses is critical.
- Observed behavior
- Parentheses are color-coded, but matching parentheses fail to appear in bold when the cursor is placed next to them.
Ensure your workbook is saved before modifying complex formulas. Check your current Office version, as visual formula indicators can fluctuate based on the specific Excel build installed on your system.
Update Microsoft Office Build
Installing the latest Office updates can resolve visual glitches or reinstate features that were modified or temporarily broken in previous rollouts.
Because Microsoft frequently pushes background updates to Office 2021 and Microsoft 365, UI behaviors like bolding parentheses can sometimes break and subsequently be fixed in newer patches.
Click on 'File' in the top left corner of the Excel ribbon, then select 'Account' at the bottom of the left-hand menu.
Click on the 'Update Options' drop-down menu located under the Product Information section.
Select 'Update Now' to force Excel to check for and install the latest available patches, then restart Excel to see if bolding returns.

Structure Formulas with Line Breaks
Since the bolding feature has become unreliable, manually formatting the formula makes matching parentheses visually obvious.

Frequently Asked Questions
Did Microsoft permanently remove bold parentheses in Excel?
Microsoft has not officially documented the permanent removal of this feature, but many users across Office 2021 and Microsoft 365 report that matching parentheses no longer turn bold. It is generally considered an unreliable feature in current builds, leaving color-coding as the primary visual aid.
How do I easily track matching parentheses in long Excel formulas?
Beyond basic color-coding, the best practice is to expand the formula bar (Ctrl + Shift + U) and use Alt + Enter to add line breaks. Formatting your formula like code across multiple lines makes it much easier to track nested functions and their closing parentheses.
Can I change the color of the parentheses in Excel?
No, Excel automatically assigns colors to parentheses based on their nesting level to help you pair them up. There is no built-in setting to customize these colors manually or force them to appear bold.
