Good morning coding comrades!

I would like to either turn off recalculation for grouping ungrouping rows,
or for changing filters on the data tab.

Or I would like to have the spreadsheet calculation off, and then turn on via vba ONLY
when a user changes a cell value. . .

The spreadsheet has about 25000 input cells within about 15 individual tabs.

Would this be a tab/class formula triggering calculation when specific cells are changed?
or a spreadsheet class vba formula?

some workbook calculations can take up to 2-3 minutes on a small laptop

Thanks
