A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi Clare,
As per checking, this is a feature limitation on iPad. The Excel mobile app (iOS/iPadOS) does not include the Chart Filter icon that you’re used to on desktop. Microsoft has streamlined the mobile interface, therefore, the advanced chart tools like Chart Filters, Select Data, and axis bound adjustments are missing.
The best option or workaround to proceed here is to use Excel Online version which you'll access it through a browser if you want to use Chart Filters without switching devices.
