Microsoft Office for iOS provides limited control over default application themes. Changing the default font from the newly implemented Aptos back to Calibri, or restoring classic chart colors globally, is not currently supported natively within the iOS app.

Frequently Asked Questions

Why did my Excel font suddenly change to Aptos on my iPhone?

Microsoft updated its default Office theme across its entire ecosystem, replacing the long-standing Calibri font with Aptos. This change automatically applied to the latest versions of the iOS apps as well, alongside an updated default color palette for charts.

Can I permanently change the default font back to Calibri in Excel for iOS?

Currently, Microsoft Office for iOS does not offer a global setting to change the default font back to Calibri. You must either manually select your text and change the font for each new document, or use a pre-formatted template.

How do I change chart colors in the iOS Excel app?

While you can alter individual chart elements by tapping the chart and using the 'Colors' formatting menu, Office for iOS does not support changing global default theme colors the way the desktop versions do.
