Hello
Kata Davis,
It sounds like Excel’s gridline color might have been changed globally, which sometimes happens after theme or display updates. Let’s go through a few checks to restore the default gridlines permanently:
- Check Gridline Visibility from the View Tab:
- Go to the View tab on the Ribbon.
- In the Show group, make sure the Gridlines checkbox is ticked.
- If it’s unchecked, gridlines won’t appear even if they’re enabled in Options.
- Reset Gridline Color:
- Go to File ➜ Options ➜ Advanced.
- Under Display options for this worksheet, make sure Show gridlines is selected.
- Set Gridline color to Automatic (not black or custom).
- Click OK to save changes.
- Apply to All Worksheets:
- If the issue persists, right-click any sheet tab → Select All Sheets → then adjust the gridline color once; it’ll apply to all sheets.
- Check Excel Theme or Display Mode:
- Dark Mode or high-contrast themes can make gridlines appear faint. Try switching to Light Mode to confirm.
- Repair or Reset Excel Profile (if needed):
- Close Excel → go to Control Panel ➜ Programs ➜ Microsoft Office ➜ Change ➜ Quick Repair.
- Or start Excel in Safe Mode (Ctrl + click Excel icon) to check if an add-in is causing the problem.
Please try enabling
View → Gridlines and setting the color to
Automatic, this usually restores the gridlines permanently.
