OpenOffice and LibreOffice Calc are powerful spreadsheet applications that offer a wide range of features, including the ability to create and edit complex formulas. However, there may be times when you need to refresh these formulas to ensure that they are up-to-date. This article will guide you through the process of refreshing formulas in OpenOffice/LibreOffice Calc.
To refresh formulas in OpenOffice/LibreOffice Calc, you can use the F9 key to recalculate formulas with volatile functions, or manually trigger a recalculation using the Recalculate command. Additionally, you can use the Shift + Ctrl + F9 keyboard shortcut to recalculate all formulas in the entire document. If you’re dealing with Add-In functions or older spreadsheets, these advanced techniques can help ensure your formulas are up-to-date.

Understanding Formulas in Calc
Formulas in Calc are expressions that perform calculations on values in your spreadsheet. They can be as simple as
=A1+B1, which adds the values of cells A1 and B1, or as complex as a multi-part function that calculates statistical data across a range of cells.
Refreshing Formulas: The Basics
There are several ways to refresh formulas in OpenOffice/LibreOffice Calc. Here are the most common methods:
Using the F9 Key
Pressing the F9 key in Calc will recalculate formulas that include volatile functions like
NOW(). These functions generate new values each time the spreadsheet recalculates.
Using the Recalculate Command
You can manually trigger a recalculation of all changed formulas by navigating to Data – Calculate – Recalculate in the menu.
Using the Keyboard Shortcut
Pressing Shift + Ctrl + F9 will recalculate all formulas in the entire document. This is similar to pressing F9 in Excel and is particularly useful when dealing with large spreadsheets.
Advanced Refreshing Techniques
Sometimes, the basic methods may not be enough. If you’re using Add-In functions or dealing with older spreadsheets, you may need to use these advanced techniques:
Recalculate Add-In Functions
Add-In functions like
RANDBETWEEN may not respond to the Recalculate command or F9. In this case, you can use the keyboard shortcut Shift + Ctrl + F9 to recalculate all formulas, including the Add-In functions.
Refreshing Display and Charts
Once the document has been recalculated, the display will be refreshed, and all charts will also be updated. This ensures that your data visualization is always in sync with your data.
Troubleshooting Formula Refresh Issues
Despite your best efforts, you may encounter issues with formulas not updating in Calc. Here are some potential solutions:
Check Memory Settings
Under Tools – Options – LibreOffice – Memory, try increasing the amount of memory allocated to LibreOffice. This may help with the recalculation process.
Check AutoCalculate Setting
Go to Data – Calculate and ensure that AutoCalculate is selected. This will enable automatic recalculation of formulas.
Recalculate Older Spreadsheets
By default, LibreOffice does not recalculate older spreadsheets to ensure compatibility with different versions or spreadsheet programs. To force recalculation, go to Tools – Options – Formula – LibreOffice Calc, and under ‘Recalculation on file load’, change the drop-downs to ‘Always recalculate’. Close and reopen the spreadsheet to see the recalculated formulas.
Replace ‘=’ in All Sheets
If formulas are not updating, you can try replacing ‘=’ by ‘=’ in all sheets. Use the keyboard shortcut Ctrl + H, mark ‘Search in all sheets’, and replace all ‘=’ by ‘=’.
In conclusion, refreshing formulas in OpenOffice/LibreOffice Calc is a straightforward process that can be accomplished with a few simple steps. Whether you’re using the F9 key, the Recalculate command, or the Shift + Ctrl + F9 keyboard shortcut, you can ensure that your formulas are always up-to-date and accurate. If you encounter any issues, the troubleshooting tips provided in this article should help you resolve them quickly and efficiently.
To refresh formulas in OpenOffice/LibreOffice Calc, you can use the F9 key, the Recalculate command, or the Shift + Ctrl + F9 keyboard shortcut. These methods will recalculate the formulas in your spreadsheet and ensure they are up-to-date.
Formulas in Calc are expressions that perform calculations on values in your spreadsheet. They can be simple, like
=A1+B1, or complex, involving functions and references to multiple cells.
Refreshing formulas ensures that they are recalculated and reflect the latest data in your spreadsheet. This is important to maintain accurate calculations and keep your data up-to-date.
If you are using Add-In functions like
RANDBETWEEN that don’t respond to the Recalculate command or F9, you can use the keyboard shortcut Shift + Ctrl + F9 to recalculate all formulas, including the Add-In functions.
If you encounter issues with formulas not updating, you can try checking the memory settings under Tools – Options – LibreOffice – Memory and increasing the allocated memory. Additionally, ensure that AutoCalculate is selected under Data – Calculate. For older spreadsheets, you may need to force recalculation by changing the recalculation settings under Tools – Options – Formula – LibreOffice Calc. Finally, if formulas are not updating, you can try replacing ‘=’ with ‘=’ in all sheets using the Ctrl + H keyboard shortcut.
