Refresh Excel VBA Function Results

Question

How can I get a user-defined function to re-evaluate itself based on changed data in the spreadsheet?

I tried F9 and Shift

Answer 1

Some more information on the F9 keyboard shortcuts for calculation in Excel

• F9 Recalculates all worksheets in all open workbooks
• Shift+ F9 Recalculates the active worksheet
• Ctrl+Alt+ F9 Recalculates all worksheets in all open workbooks (Full recalculation)
• Shift + Ctrl+Alt+ F9 Rebuilds the dependency tree and does a full recalculation
