Question
Answer and Explanation
The issue of Excel multipage not refreshing can stem from a variety of factors related to how Excel manages its calculations and data. Here are some common reasons and solutions:
1. Calculation Mode:
- Excel has three calculation modes: Automatic, Automatic except for data tables, and Manual. If your workbook is set to Manual, formulas won't update automatically. To check and change this, go to "Formulas" > "Calculation Options" and select "Automatic".
2. Circular References:
- A circular reference occurs when a formula refers back to itself, either directly or indirectly. Excel often freezes to prevent endless recalculations in such cases. To identify and resolve them, go to "Formulas" > "Error Checking" > "Circular References".
3. Large or Complex Formulas:
- Extremely large, complex, or volatile formulas (like =NOW() or =RAND()) can slow down recalculation across multiple sheets. Review these formulas and consider simplifying or optimizing them. Use functions such as =TODAY() instead of =NOW() if you do not need to update every second.
4. Data Connections and External Links:
- If your Excel workbook contains data connections to external databases, websites or files, they may not refresh as expected, especially if these external sources are unavailable or slow. Go to "Data" > "Queries & Connections" to check data connections and refresh settings.
5. Worksheet Protection:
- If a worksheet or the workbook is protected, it might prevent cells from recalculating as expected. Unprotect the worksheet by going to "Review" > "Unprotect Sheet". Make sure this does not affect your data security.
6. Excel Add-ins:
- Certain Excel add-ins can sometimes interfere with calculation processes. Try disabling all add-ins temporarily to see if that resolves the issue. Go to "File" > "Options" > "Add-ins" and select "Excel Add-ins" in "Manage" and click "Go." Uncheck the add-ins and click "OK".
7. File Corruption:
- Sometimes, a file may be corrupt, causing unexpected behavior. In such cases, try saving the file as a new copy or attempt to open it using 'Open and Repair' by going to "File" > "Open" > Select the file and click the drop down arrow on 'Open' button and select 'Open and Repair'.
8. Hardware Resources:
- If your computer lacks sufficient RAM or processing power, Excel may struggle to recalculate large or complex worksheets across multiple sheets efficiently. Close unnecessary applications and consider upgrading hardware if necessary.
By checking these areas, you should be able to diagnose and resolve the reason why your Excel multipage is not refreshing as expected. Understanding Excel's calculation modes and dependencies is vital for maintaining smooth workbook operations.
