• Choose the column(s) that you want Excel to consider when identifying duplicates. You can select one or multiple columns.
• Click on the "OK" button to remove the duplicate text values from your dataset.

Utilizing formulas or functions

If you prefer a more flexible approach to removing duplicate text values, you can use formulas or functions in Excel. One commonly used formula is the INDEX-MATCH combination:

• Start by inserting a new column next to the column containing the text values.
• In the first cell of the new column, enter the formula =IF(COUNTIF($A$2:A2,A2)>1,"Duplicate",""), assuming your text values are in column A and that the first row is a header row. Adjust the formula references accordingly for your dataset.
• Drag the formula down to apply it to all cells in the column.
• Filter the new column by "Duplicate" and delete the filtered rows to remove the duplicate text values.

Additionally, you can use the RemoveDuplicates function in VBA (Visual Basic for Applications) to automate the removal process using a macro.

Customizing the removal process based on specific needs

Excel offers various options to customize the removal process based on your specific needs. When using the Remove Duplicates feature, you can choose to keep the first or last occurrence of duplicate text values, retaining the most recent or oldest data, respectively.

Furthermore, you can combine different criteria to determine duplicates by selecting multiple columns during the Remove Duplicates process. This allows you to consider combinations of columns to find unique records based on specific fields.

By taking advantage of these customization options, you can fine-tune the removal process to align with your unique requirements and achieve the desired outcome.
