In this section, we will delve into advanced filtering techniques in Excel. Filtering is a powerful tool that allows you to display only the data that meets certain criteria, making it easier to analyze and work with large datasets. Advanced filtering techniques go beyond the basic filter options and provide more control and flexibility.

1. Basic Filtering Recap:

   • AutoFilter: Quickly filter data based on specific criteria.
   • Custom AutoFilter: Create more complex filters using conditions like "greater than," "less than," etc.

2. Advanced Filter:

   • Criteria Range: Define complex criteria using a separate range of cells.
   • Copy to Another Location: Extract filtered data to a different part of the worksheet.

3. Using Wildcards:

   • Asterisk (*): Represents any number of characters.
   • Question Mark (?): Represents a single character.

4. Filtering with Formulas:

   • Use formulas to create dynamic criteria for filtering.

1. Setup Data:
