Before you start

Pay attention to the Create a backup copy of the worksheet checkbox. We recommend keeping this option selected as Excel doesn't let you cancel changes made by add-ins.

Note that hidden rows are still processed by the add-in.

How to use Merge Duplicates

Start Merge Duplicates

On the Ablebits Data tab in the Merge group, click the Merge Duplicates icon:
Start Merge Duplicates for Excel.

Step 1: Select your table

On the first step, the add-in picks the entire range with your data:
Select your table to merge duplicates.

  • To specify a different range, click the Select range icon in the add-in window.
  • You can also select the records right in the worksheet, the add-in will pick up your selection.
  • Another option is to type the range address in the Select your table field manually.
Note. If your data is formatted as a table, the add-in will always get the entire table.
Note. If you have hidden rows in your table, they will be processed.

Do not forget to tick the Create a backup copy of the worksheet checkbox to have a copy of your data.

Click Next.

Step 2: Choose key columns with duplicate records

On this step, you can see a list of all columns you have in your Excel sheet:
Select key columns with duplicates to merge.
Pick the columns where you want to find duplicate entries. If you select more than one column, a record will be considered duplicate if values in all the selected key columns are the same.

  • If you have header rows, tick off the My table has headers checkbox at the top. If you do not have labels, look at 1st row content to understand what kind of data the columns contain.
  • Select the Skip empty cells option if you have blanks in your key columns and don't want to merge them. Unselect the checkbox to consider blank values as duplicates.
  • Take advantage of the Select All button if all the columns in your table are the key ones. Use Unselect All if you picked the wrong columns.
Tip. If you have a lot of columns in your table, you can expand the wizard window by dragging the bottom-right corner down and to the right until you get a suitable size.

Click the Next button.

Step 3: Pick columns with the values to merge

On this step, select the columns with the entries to merge:
Pick columns with the values to merge with the Merge Duplicates tool.
Tick the checkboxes next to the columns with the data you need to combine and take advantage of the advanced options:

  • Check Delete duplicate values if the records you need to combine may contain identical items but you want to keep only unique values in your results:
    Merge duplicates and delete duplicate values.
  • Select the Skip empty cells option to avoid adding extra delimiters to blank cells.
  • To use the same delimiter in each column, click the Choose delimiter drop-down list at the top. You can either enter your own separator or select one from the predefined options. Standard delimiters include a semicolon, comma, space, and a line break. Besides, you can select one of the following aggregate functions: AVERAGE, SUM, COUNT, MAX, MIN, PRODUCT, STDEV.S, or STDEV.P:
    Select delimiters for merged values. Choose aggregate functions.
  • Note. The tool uses the standard Excel functions (SUM, AVERAGE, COUNT, MAX, MIN, PRODUCT, STDEV.P, STDEV.S), so if you face certain difficulties, please consult a corresponding section here.
  • If you wish to have different delimiters for each column, enter or select the needed ones in the Delimiter field next to the column name:
    Choose a different delimiter for each column.
  • The Select All and Unselect All buttons help you quickly pick all the columns or unselect them at once.
Tip. If you need to change your settings on the previous steps, click the Back button and make the necessary corrections.

Click Finish to get the duplicates in the selected columns merged:
