# Remove Duplicates This action removes all the rows that are duplicate. {% hint style="warning" %} It is best practice to always specify a column, unless you have a very special case. Specifying a column will make your TaskBot run faster. {% endhint %} Notes: Files in *file* columns will be ignored when searching for duplicates. The TaskBot will remove **the latest (the newest) rows** and preserve previous rows per default. If you want to reverse this behavior, then check the checkbox *Preserve newest rows* (note that this option is only available in native tables and not available for Google Sheets). ### Do Not Place Inside Loops This is a batch operation. This means that all table rows - no matter how many there are - are fetched and the duplicate removal is applied to the whole table. Hence, it does not make sense to use this on every loop iteration. {% hint style="warning" %} If you place this building block inside a loop, duplicates will only be removed once. {% endhint %} ### Video Tutorial {% embed url="" %}
