Frequently Asked Questions
What are stale values in an Excel spreadsheet?
Stale values occur when a workbook is set to manual calculation mode, and a cell's input has changed but the formula cell depending on it hasn't been recalculated yet.
Why do stale values suddenly show as a strikethrough?
Excel introduced a visual indicator feature that crosses out (strikethrough) stale values. This is designed to warn users that the data displayed in the cell is outdated and pending a recalculation.
How do I recalculate cells to remove the strikethrough automatically?
You can force a manual calculation for the entire workbook by pressing the F9 key, or you can change your calculation options back to 'Automatic' under the Formulas tab.
Why can't I find 'Format Stale Values' in my Calculation Options?
Depending on your specific version or update channel of Excel, this option might not be present in the ribbon. Instead, you need to navigate to File > Options > Formulas and uncheck 'Cells containing stale values' under the Error checking rules.
