2. Using AND/OR Functions: To apply formatting based on multiple conditions, use the `AND()` or `OR()` functions. For example, `=AND(A1>10, A1<20)` will only highlight cells with values between 10 and 20.

3. Highlighting Entire Rows: To highlight an entire row based on a single cell's value, use a formula like `=$A1>10`. The dollar sign fixes the column, allowing the condition to apply across the row.

4. Using Cell References: Instead of hardcoding values, use cell references in your formulas. For example, `=A1>$B$1` will compare the value in A1 with a fixed threshold value in B1.

5. conditional Formatting with dates: Use formulas to format cells based on dates. For instance, `=TODAY()-A1>30` can highlight dates that are more than 30 days old.

6. Using Functions Like COUNTIF: Incorporate functions like `COUNTIF` to apply formatting based on the frequency of a value. For example, `=COUNTIF($A$1:$A$10, A1)>1` will highlight duplicate values in the range A1:A10.

7. Applying Formatting Based on Another Cell's Value: Create a rule like `=A1=B1` to format cells in column A when they match the corresponding cell in column B.

8. Using indirect for Dynamic ranges: The `INDIRECT` function can be used to reference ranges dynamically. For example, `=SUM(INDIRECT("A"&ROW()&":A"&ROW()+4))>100` will sum the next five cells and apply formatting if the total is greater than 100.

9. Highlighting Top/Bottom Values: Use `=RANK.EQ(A1,$A$1:$A$10,0)<=3` to highlight the top 3 values in a range.

10. Custom Formulas for Data Bars: Instead of using the default settings, create a formula like `=A1/MAX($A$1:$A$10)` to set the length of data bars relative to the maximum value in the range.

For example, if you're tracking sales performance, you could use a formula to apply a green color scale to sales figures that exceed the monthly target, a yellow color for those near the target, and a red color for figures below the target. This not only makes the data more visually appealing but also instantly communicates performance levels without the need for in-depth analysis.

Remember, the key to effectively using formulas with conditional formatting is understanding the logic behind the conditions you want to set and how they relate to your data. With practice, you can leverage these tools to make data-driven decisions faster and more accurately.
