# Use the Join component

# Use the Join component {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Concatenate the elements of an array into a string by using the Join component in RPA Desktop Design Studio.

## Before you begin

Role required: none

## About this task

You can concatenate the elements of an array into a string by applying a specified separator such as dot, comma, or pipe. For example, if the string is {"Apple", "Banana", "Orange"} and separator is dot (.), then the
concatenated string would be "Apple.Banana.Orange".

You can configure the properties for the Join 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 Join 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 Join component to the corresponding ports of the other components as described in the following table.  
   {#use-stringutil-join__table_jnw_jn1_krb__entry__4}

   | Parameter name | Description | Data Port type | Data type |
   |-|-|-|-|
   | StringArray | Specify a string array that you want to concatenate or use the string array from the previously executed component. | Data In | String\[\] |
   | Separator | The text separator that joins the arrays such as dot (.), comma (,), or pipe (\|). | Data In | String |
   | String | Returns concatenated string as an output that you can use in the next component. | Data Out | String |
