## How to Use the WCase() Function in Report Custom Columns?
In this tutorial, you will learn how to use the `WCase` function to **capitalize the first letter of each word** in a string while converting the remaining characters to lowercase.
***
### Accessing the Expression Designer:
* Open Sale Voucher or any document.
* Navigate to the "**Setup Column Attributes"**.
* Here, you'll see a list of available columns that can be used to build expressions.
* Click on **"Add/Edit Expression Columns"** where you can write your expression using predefined functions.
### Writing Your First Expression
* Every expression must start with the script header: **'#@LSCRIPT**
* Click the (+) Plus icon to create a new expression.
* Fill in the required fields:
* **Expression Name** – A unique name for your expression.
* **Expression Type** – Choose either **Text** or **Numeric** depending on the expected output.
* Double-click the new expression name to insert it into the script editor.
* Define the expression using the syntax:
* Expression Name = WCASE("ITEM\_NAME")
* Capitalize the **first letter** of each word in a field and convert the rest to lowercase.
* Save the expression.
* Scroll down and check the box next to your expression name to **enable the column** in the grid.
* The grid now shows the **item names in title case** (first letter capitalized, rest in lowercase).
***
### Applying the Expression in a Report
* Navigate to the **Reporting** section.
* Open the **Sales Register Detailed Report** or any **"Report".**
* Go to **Setup Column Attributes** as you did earlier.
* Before adding the expression to the report, go to **Other Settings**.
* Ensure the **Script Editor** is set to **VBScript**.
* Click **Save**.
* *Note: VBScript is the default for new configurations but always verify this setting.*

### Adding and Using the Expression in the Report
* Return to **"Setup Column Attribute"** window.
* Click **"Add/Edit Expression Columns"**.
* Every expression must start with the script header **'#@LSCRIPT**
* Click the (+) Plus icon to create a new expression.
* Fill in the required fields:
* **Expression Name** – A unique name for your expression.
* **Expression Type** – Choose either **Text** or **Numeric** depending on the expected output.
### Creating a Simple WCASE() Expression
* Double-click your newly created expression to insert it into the script editor.
* Define the expression using the syntax:
* Expression Name = WCASE("ITEM\_NAME")
* Capitalize the **first letter** of each word in a field and convert the rest to lowercase.
* Click **Save**.
* Scroll down and **check the box** to enable the column in the report.
* Save and proceed to check the effect.
* **Refresh the report** to view the final result.
***
### Summary
* The `WCase` function transforms each word in the selected field (e.g., party name or item name) into **title case**.
* Useful for reports requiring **clean, uniform, and professional text formatting**.
