I followed the directions but for some reason my conditional formatting rule is highlighting cells outside of the logic that I have set. Any ideas why it might be doing this? This is my formula: =LEFT(L2,1)="A"

But Excel is highlighting certain cells that start with "G" and I cannot see why it is doing this.

Hi Anhthu Huynh,
Can you provide a screenshot of your data, or upload a sample file here? This formula helps to highlight cells that start with the character "a" or "A" in the selected range. For highlighting the cells that start with "G", I can't find a reason yet.

Or...just do conditional formatting with the "text that contains" option. Home > Conditional Formatting > Highlight Cells Rules > Text that contains

If one alphabet is repeated continue 9 time 10th one it's should show warning or indication .
Example in A1 cell to A9 cell "P" is repeated if I tried to write is A10 cell P meas it's should show a warning or indication .
