# Split Columns
In this document, you will explore how to split columns in Astera Dataprep.
1. To split columns in Astera Dataprep, click on the *Layout* option in the toolbar and select the *Split Columns* option from the drop-down.
2. This will open the *Recipe Configuration – Split Columns* panel.
3. In this panel, you can configure the following options:
* **Column Name:** Choose the column you want to split.
* **Delimiter:** Enter the character (like a space, comma, or dash) that separates the values.
* **New Column Names**: Specify the names for the new columns that will hold the split values.
4. Once you're done, click Apply 
. You’ll see in the Grid that your selected column (for example, *CustomerName*) has been split into new columns (like *FirstName* and *LastName*) based on the delimiter you provided*.*
5. Alternatively, you can right-click on a column header directly in the Grid and select *Split Columns* from the menu. The configuration panel will open with the selected column pre-filled. Make any changes you need and click *Apply*  to split the column.
