Microsoft 365 Insider Program Introduces Excel Performance Optimization Feature

Excel for Windows gets a new feature to clean up workbooks and improve performance.


has unveiled a new feature for the Windows version of Microsoft Excel, aimed at enhancing workbook performance by identifying and rectifying unnecessary formatting and metadata. Initially introduced to the web edition of Excel in September 2022, this update is now accessible to members of the Microsoft 365 Insider program. The feature is designed to automatically detect cells that may be slowing down the workbook due to redundant formatting, a common issue in large worksheets over time.

How the Optimization Feature Works

Upon opening a workbook, Excel will automatically scan for cells with unnecessary formatting. If such cells are detected, users will be prompted with a “Slow Workbook?” notification, accompanied by a “Check Performance” button. This proactive approach allows users to address performance issues promptly. Additionally, users have the option to manually initiate the performance check by selecting the “Check Performance” button found under the Review tab in the top menu ribbon. The Workbook Performance pane, once opened, provides insights into problematic cells, offering users two methods to identify and resolve issues that may be impacting workbook performance.Check-Performance-Excel-Windows

Considerations and Availability

Microsoft has cautioned that the use of this performance optimization feature may lead to visual changes in the workbook. Users may need to manually adjust the visual aspects of their workbook if such changes occur. This update is currently available to users participating in the Insider program, specifically those on the Beta Channel running Version 2312 (Build 17126.20004) or later. This development represents Microsoft's ongoing efforts to enhance user experience and software performance, addressing common inefficiencies that can hinder productivity in Excel.
