# Change Case
In this document, you’ll learn how to use the Change Case function in Astera Dataprep to convert text data to lower, upper, or title case.
1. To begin, click on the *Cleanse* option in the toolbar and select *Change* *Case* from the drop-down.
2. This will open the *Recipe Configuration – Change Case* panel.
3. In this panel, you’ll configure the following options:
* Column Selection Properties
* **Apply to entire dataset**: Applies the case change to all columns in the dataset.
* **Apply to specific column(s)** – Applies the change only to selected columns.
* Case Type
* **Lower**: Converts all text to lowercase.
* **Upper:** Converts all text to uppercase.
* **Title**: Capitalizes the first letter of each word.
4. Once you’re done, click *Apply* *.* In the Grid, you’ll see that the data in the *StoreName* column has been converted to uppercase.
5. Alternatively, you can right-click on a column header in the Grid and select *Cleanse > Change Case.* The same configuration panel will appear with the column already selected. Make any changes you need and click *Apply* to update your data.
