How To Remove Non Duplicates In Excel

Excel users often need to manage data by identifying and removing non-duplicates, ensuring uniqueness across datasets. This task can be complex and time-consuming within native Excel functions.

The process typically involves using formulas or conditional formatting to highlight unique data before manually or programmatically removing it. However, these methods can be error-prone and require a solid understanding of Excel formulas and features.

We'll explore how Sourcetable simplifies the removal of non-duplicates, offering a more intuitive and user-friendly alternative to the manual processes in Excel.

How to Remove Non-Duplicates in Excel

Using COUNTIF and Filters

To remove non-duplicate records in Excel, add a new column utilizing the COUNTIF function to differentiate unique entries. Label each row as "unique" or "duplicate" based on the COUNTIF result. Then, apply a filter to the entire table to display only the unique values marked by the COUNTIF formula. Complete the process by deleting the filtered rows, effectively removing all non-duplicates from your dataset.

Remove Non-Duplicates with VLOOKUP and Unique ID

Another method involves generating a column for unique IDs beside your data. Copy your table to a new sheet and apply the 'Remove Duplicates' feature, excluding the unique ID column. Back in the original sheet, you can use a basic VLOOKUP to pinpoint non-duplicates. After identifying them, filter and delete these unique rows to retain duplicates only.

Sorting and Deleting Unique Entries

An alternative approach is to highlight duplicates directly in a column and enable Excel's filter option. By sorting the column according to cell color, you can isolate non-duplicates. Removal is straightforward; simply delete these highlighted non-duplicate entries to keep only the duplicate records.

Power Query Editor for Duplicates

For advanced manipulation, use the Power Query Editor. Select any cell within your data, navigate to the 'Query' tab, and opt for 'Edit'. Under 'Home', choose 'Keep Rows' followed by 'Keep Duplicates'. This command filters the data to display exclusively duplicate rows, after which you can delete non-duplicates with ease.

Filter vs. Remove Duplicates

It's essential to differentiate between filtering for unique values with the 'Advanced Filter' command and the permanent deletion of duplicates using 'Remove Duplicates'. Filtering only hides non-duplicates temporarily, while removing duplicates discards them entirely, maintaining just the first instance of duplicate entries within your data.
