A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi SLG75,
Welcome to Microsoft Community.
If you prefer to work with your data in Excel Online, you can format the cells as Date, then double-click a cell to enter edit mode, which will trigger the built-in date picker in Excel Online. This date picker is a browser-based feature developed by Microsoft.
If you would rather use a native Date Picker add-in in the Excel desktop application, it is available in the 32-bit version of Excel (Developer>Insert>More Controls>Microsoft Date and Time Picker Control 6.0).
For the 64-bit version of Excel, a more suitable option with a more visually appealing interface is a third-party add-in from the Excel Add-in Store. I recommend Mini Calendar and Date Picker add-in, which can be downloaded directly from the Excel Add-in Store.
Once the add-in is enabled, a small window will appear above your worksheet. Simply click on a date, and it will be inserted into the selected cell.
I hope the information above is helpful to you. If you have any other questions or want to share more context, please let me know in your reply!
Best Regards,
