Step-by-Step Guide to Utilizing Drop Duplicate Rows#

Column Selection#

Select the column from the dropdown menu for which you would like to eliminate duplicates.

Select Entries to Keep or Drop#

When dealing with duplicate entries in your dataset, you can choose from the following options to determine how they should be processed

Handling Duplicates#

When dealing with duplicate entries in your dataset, you can choose from the following options to determine how they should be processed:

Keep First

• Definition

  Retains only the first occurrence of each duplicate entry and removes subsequent duplicates.

• How it Works

  The dataset is processed in its existing order, and when duplicates are encountered, only the first one is kept.

Keep Last

• Definition

  Retains the most recent occurrence of each duplicate entry while removing earlier instances.

• How it Works

  The dataset is processed in its existing order, and when duplicates are encountered, only the last one is kept.

Drop All

• Definition

  Completely removes all occurrences of duplicate entries, leaving only unique values in the dataset.

• How it Works

  If a value appears more than once, all instances of that value are removed, meaning neither the original nor the duplicate remains.

Repeat for Additional Columns#

Click Add New Column to apply the same operation to additional columns if necessary. Repeat the process for each column from which you would like to drop duplicates.

Submit#

Submit the operation to execute the duplicate removal and cleanse your dataset.
