Determine whether the text is null or an empty string by using the IsNullOrEmpty
component in RPA Desktop Design Studio.

## Before you begin

Role required: none

## About this task

You can configure the properties for the IsNullOrEmpty component. For more
information about these properties, see [Properties of the String Utilities components](https://www.servicenow.com/docs/T2CwwgGDMWnWXB0oo5BP8A "Learn about the properties of the String Utilities components in RPA Desktop Design Studio.").

## Procedure

1. In the Toolbox pane, navigate to UtilitiesString Utilities.
2. Drag the IsNullOrEmpty component to the Design surface.
3. To configure the input fields, see [Configure port properties](https://www.servicenow.com/docs/o6fErdzBCUqYUWlLG1ZZzQ "Configure how data is passed to the input fields of a component or method in RPA Desktop Design Studio.").
4. Connect the data and control ports of the IsNullOrEmpty component to the corresponding ports of the other components as described in the following table.  
   {#use-stringutil-isnullempty__table_jnw_jn1_krb__entry__3}

   |-|-|-|
   | Data In (Text) | Takes the text that the component evaluates from a previously executed component. | Yes |
   | Data Out (Boolean) | Returns the Boolean response to whether the text is null or empty and passes the value to the next component. | Yes |
   | Control In | Connects to the Control Out port of one or more components. | Yes |
