In Excel, there are several ways to filter for unique values—or remove duplicate values:

  • To filter for unique values, click Data > Sort & Filter > Advanced.

  • To remove duplicate values, click Data > Data Tools > Remove Duplicates.

  • To highlight unique or duplicate values, use the Conditional Formatting command in the Style group on the Home tab.

Learn about filtering for unique values or removing duplicate values

Filtering for unique values and removing duplicate values are two similar tasks, since the objective is to present a list of unique values. There is a critical difference, however: When you filter for unique values, the duplicate values are only hidden temporarily. However, removing duplicate values means that you are permanently deleting duplicate values.

A duplicate value is one in which all values in at least one row are identical to all of the values in another row. A comparison of duplicate values depends on the what appears in the cell—not the underlying value stored in the cell. For example, if you have the same date value in different cells, one formatted as '3/8/2006' and the other as 'Mar 8, 2006', the values are unique.

Check before removing duplicates: Before removing duplicate values, it's a good idea to first try to filter on—or conditionally format on—unique values to confirm that you achieve the results you expect.

Filter for unique values

Follow these steps:

  1. Select the range of cells, or ensure that the active cell is in a table.

  2. Click Data > Advanced (in the Sort & Filter group).

  3. In the Advanced Filter popup box, do one of the following:

To filter the range of cells or table in place:

  • Click Filter the list, in-place.

To copy the results of the filter to another location:

  • Click Copy to another location.

  • In the Copy to box, enter a cell reference.

  • Alternatively, click Collapse Dialog to temporarily hide the popup window, select a cell on the worksheet, and then click Expand .

  • Check the Unique records only, then click OK.

The unique values from the range will copy to the new location.

Remove duplicate values

When you remove duplicate values, the only effect is on the values in the range of cells or table. Other values outside the range of cells or table will not change or move. When duplicates are removed, the first occurrence of the value in the list is kept, but other identical values are deleted.

Because you are permanently deleting data, it's a good idea to copy the original range of cells or table to another worksheet or workbook before removing duplicate values.

Follow these steps:

  1. Select the range of cells, or ensure that the active cell is in a table.

  2. On the Data tab, click Remove Duplicates (in the Data Tools group).

  3. Do one or more of the following:

    • Under Columns, select one or more columns.

    • To quickly select all columns, click Select All.

    • To quickly clear all columns, click Unselect All.

      If the range of cells or table contains many columns and you want to only select a few columns, you may find it easier to click Unselect All, and then under Columns, select those columns.

      Note: Data will be removed from all columns, even if you don't select all the columns at this step. For example, if you select Column1 and Column2, but not Column3, then the “key” used to find duplicates is the value of BOTH Column1 & Column2. If a duplicate is found in those columns, then the entire row will be removed, including other columns in the table or range.

  4. Click OK, and a message will appear to indicate how many duplicate values were removed, or how many unique values remain. Click OK to dismiss this message.

  5. Undo the change by click Undo (or pressing Ctrl+Z on the keyboard).

Problems removing duplicates from outlined or subtotaled data

You cannot remove duplicate values from outline data that is outlined or that has subtotals. To remove duplicates, you must remove both the outline and the subtotals. For more information, see Outline a list of data in a worksheet and Remove subtotals.

Conditionally format unique or duplicate values

Note: You cannot conditionally format fields in the Values area of a PivotTable report by unique or duplicate values.

Quick formatting

Follow these steps:

  1. Select one or more cells in a range, table, or PivotTable report.

  2. On the Home tab, in the Style group, click the small arrow for Conditional Formatting, and then click Highlight Cells Rules, and select Duplicate Values.
