How to set English as the default input language for Excel on MacBook Pro

Dear Microsoft Support,

I am experiencing an issue with Microsoft Excel for Mac (Version 16.95, Microsoft 365 Subscription) on my MacBook Pro (macOS Sequoia 15.2).

My Mac keyboard settings are configured for two input sources:

• English (Canadian)
• Russian (PC)

However, each time I open Excel and start typing, the input language in the MacBook top panel automatically switches to Russian instead of remaining in English (Canadian), which is my preferred input method. This happens regardless of my previous settings, and I have to manually change it back to English each time.

I have checked the following:

• My macOS Language & Region settings are set to English (Primary) and Russian (Secondary).
• In System Settings > Keyboard > Input Sources, automatic language switching is disabled.
• In Excel’s Language Preferences, English is set as the application language.

Despite these settings, Excel consistently defaults to Russian upon startup, causing significant workflow disruption.

Could you please provide guidance on how to permanently set English as the default input language for Excel, or at least prevent Excel from changing my system language settings?

Thank you for your assistance.

Best regards,

Taisiya
