- Specify the criteria range and copy the unique results to a new location.
Step-by-Step Guide to Effective Data Filtering
1. Identify the Column: Determine the column containing the unique entries you want to filter.
2. Apply the Filter: Use the AutoFilter feature or Advanced Filter to display only unique values.
3. Refine the Filter: Utilize filter options to further narrow down the data based on specific criteria.
Tips and Tricks for Efficient Data Filtering
1. Use Custom Filters:
