- Scenario
- Managing a call log where data appearance has been suddenly altered due to an accidental setting change or keystroke.
- Observed behavior
- Dates, times, and phone numbers display incorrectly, often appearing as raw serial numbers or underlying formulas instead of their intended formatted appearance.
Before manually changing any cell formatting, verify that you haven't accidentally switched your worksheet to 'Show Formulas' mode, which displays raw underlying data and formulas instead of their formatted results.
Disable the Show Formulas Feature
Often, formatting appears broken because the spreadsheet is displaying raw formulas and underlying values instead of the formatted results. Turning this feature off will instantly restore normal display.
The 'Show Formulas' feature is useful for auditing your spreadsheet, but when accidentally enabled, it removes all number and date formatting, displaying the underlying serial numbers and formulas instead.
Click on the 'Formulas' tab located in the top ribbon of your spreadsheet application.
Find the 'Formula Auditing' group within the Formulas tab.
Check if the 'Show Formulas' button is highlighted. If it is, click it to turn it off. Alternatively, you can press the keyboard shortcut Ctrl + ` (grave accent) to toggle this view off.

Reapply Number, Date, and Time Formatting
If 'Show Formulas' is already disabled but the data still looks wrong, you will need to manually reapply the correct number formats to the affected cells.

Frequently Asked Questions
Why did my Excel dates suddenly change to 5-digit numbers?
Spreadsheet software stores dates as sequential serial numbers. If the cell formatting is accidentally changed to 'General' or 'Number', a date like January 1, 2024, will display as 45292. Simply change the format back to 'Date' using the Format Cells menu to fix this.
How do I format a cell to display a phone number correctly?
Select the cell, press Ctrl + 1 to open the Format Cells dialog box, go to the Number tab, select 'Special' under the Category list, and then choose 'Phone Number'. This applies standard phone number formatting like (555) 555-5555.
Is there a keyboard shortcut to toggle Show Formulas?
Yes, you can quickly toggle between displaying normal cell values and underlying formulas by pressing the Ctrl + ` (grave accent) shortcut on your keyboard.
