How to quickly find duplicates in a single table (list)
If you often work with similar tables, Quick Remover tool lets you quickly find duplicates in a single table. Just follow these simple steps:
- Open Excel workbook with the table and select the range you want to search in.
Then open Quick Remover by clicking on its icon
or pressing the Ctrl+Shift+D hotkey.
If you work in Excel 2003 - 2000, you can also go to Excel menu -> Ablebits.com -> Duplicate Remover for Excel -> Quick Search
Tip: Before opening Quick Remover, select any cell from your list (table/range). The wizard will automatically select the entire table.
- Define the settings for the search:
- Select columns to be searched for duplicates.
All columns are selected by default. If you have a lot of columns in your table, take advantage of the Uncheck All button and all the columns in the list will be deselected. Then you can tick those you need to search in.
Note! If you select more than one column, the add-in looks for "row" duplicates. So if you select 2 columns, only those records that have the same values in both columns will be considered duplicates. E.g.
If "Fisher 36 Oak Drive" is duplicated on another row, the add-in will find it.
If your purpose is to compare column A to column B, then use Advanced Wizard and choose the option to "Compare two tables" on step 1, select column A as your first table and column B as your second table.
- It may be helpful to indicate that there are header rows in your table. As a rule, the add-in indicates headers automatically. If it didn't, you can check the My table has headers option. This will let you see what kind of information you have in the columns. You can also uncheck this option if you don't want header rows to be indicated.
If your table doesn't have headers, you can see what kind of information is in the columns by looking at the 1st row content column next to the columns.
- You can choose to ignore extra spaces.
You should tick the Ignore extra spaces in matching columns checkbox if your data may have some extra leading or trailing spaces. This option will prevent the add-in from missing some values.
- If you may have empty cells in your search range, you can tick the Ignore empty cells option and exclude such cells from the search.
- Choose what you want to do with the found entries:
- Delete the rows with the found duplicates.
- Color values. This will change the background color of the found rows.
- Select found duplicates. In this case the rows with the found entries will be selected in your main table.
- Add a status column to your list to see if a row contains duplicates.
- Click "Run" and enjoy the results!
