I've implemented advanced conditional formatting in a sales report to categorize and visualize sales performance. By applying different formatting rules based on specific sales targets, I was able to highlight cells showing above-target or below-target sales. This made it simple to identify areas of improvement and success at a glance.

One example of using advanced conditional formatting in Excel is to highlight cells based on multiple criteria. For instance, I have used it to highlight overdue tasks in a project management spreadsheet where the due date has passed and the task status is not marked as complete. This helps me easily identify tasks that need immediate attention and follow-up.

I recently worked on a project tracking spreadsheet using Excel's advanced conditional formatting. I used it to apply data bars to a range of values in a column. This helped me visualize the progress of each project, allowing me to easily identify the ones lagging behind or making exceptional progress.

In a budgeting spreadsheet, I used advanced conditional formatting to dynamically color-code expenses based on their variance from the planned budget. It allowed me to quickly identify which expenses were under or over budget, enabling better decision making and proactive cost control.
