# Remove Columns
In this document, you will explore how to remove columns in Astera Dataprep.
1. To begin, open your recipe in Astera Dataprep. Then, click on the *Layout* option in the toolbar and select *Remove Columns* from the drop-down.
2. This will open the *Recipe Configuration – Remove Columns* panel.
3. In this panel, use the *Column Name(s)* drop-down to select the columns you want to remove. You can select multiple columns from the list.
{% hint style="info" %}
**Note:** Avoid selecting the same column more than once, as this will result in an error.
{% endhint %}
4. Once you're done, click *Apply* . The selected columns will be removed from the Grid.
5. Alternatively, you can right-click on a column header directly in the Grid and select *Remove Columns* from the menu. The configuration panel will open with the selected column pre-filled. You can further configure the columns to be removed and add any others if needed. Once done click *Apply* to remove the column(s).
