Smart View for Office Alternatives

We'd like to explore alternatives to SmartView (used in Excel to view our traditional P&L), as we’ve been encountering repeated crashes and delays.

We’re wondering if someone can suggest an alternative that provides the same live views, perhaps through an online option rather than relying on Excel-based SmartView. The frequent crashes during critical month-end periods have significantly slowed the team’s work. We're aware that Power BI can be an option, but I’d prefer to see if someone has a more direct solution first. Thank you!
