Troubleshooting Common Issues

While conditional formatting is generally straightforward, you may encounter a few hiccups:

  • Dates Not Highlighting: Make sure your date cells are formatted as actual dates and not text. Check the format by selecting the cell and looking in the format dropdown in the Home tab.
  • Formula Issues: Ensure your cell references in the formulas are correct and reflect the top-left cell of the selected range.
  • Unwanted Formatting: If the formatting applies incorrectly, review your formulas and ensure you’ve selected the correct range initially.
