While Excel doesn't directly filter by cell color or font formatting itself, you can achieve this with a two-step process:

1. Identify cells based on formatting:
- Manual check: If you have a small dataset, you can visually identify cells with the desired formatting.
- Conditional Formatting Rules (complex formatting): If you have complex formatting rules, you can't directly filter by them. However, you can create a helper column with a formula like `=GET.CELL.COLOR(A1)` (replace A1 with your actual cell reference) to return the color code. Then filter based on the color code in this helper column.
2. Filter based on identified cells:
- Once you have identified cells with the desired formatting (manual check or helper column), you can filter by cell color:
- Click the filter arrow on the desired column header.
- Choose "Filter by Color" and select the specific color you want to filter by.
- You can similarly filter by font color using the "Font Color" option in the filter dropdown menu.
