# Use the ChangeExtension component {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Change the extension of a file by using the ChangeExtension component in RPA Desktop Design Studio.

## Before you begin

Role required: none

## About this task

You can configure the properties for the ChangeExtension component. For more
information about these properties, see [Properties of the File components](https://www.servicenow.com/docs/yAiClLI5WYB22g9JOtBzWw "Learn about the properties of the File components in RPA Desktop Design Studio.").

## Procedure

1. In the Toolbox pane, navigate to UtilitiesFile.
2. Drag the ChangeExtension component to the Design surface.
3. To configure the input fields, see [Configure port properties](https://www.servicenow.com/docs/ED3jBpqtlHH8p~yFFmyRBQ "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 ChangeExtension component to the corresponding ports of the other components as described in the following table.  
   {#use-file-changeextn__table_jnw_jn1_krb__entry__3}

   | Port type | Purpose of connection | Mandatory? |
   |-|-|-|
   | Data In (Path) | Takes the path to the file for which the method changes the extension from a previously executed component. | Yes |
   | Data In (Extension) | Takes the new extension that the method changes from a previously executed component. | Yes |
   | Data Out | Returns the path with the changed extension and passes to the next component. | Yes. To preview the data, right-click the Return field and click Preview Data. |
   | Control In | Connects to the Control Out port of one or more components. | Yes |
   | Control Out | Connects to the Control In port of another component or the default end component. | No. Connecting the port is optional. |

5. **Optional:** To test the component, under the DESIGN tab, click Run.

## ChangeExtension component {#use-file-changeextn__example_wks_hjf_ggc}

Your RPA robot processes a batch of report files downloaded with `.txt` extension. To ensure consistency and compatibility with downstream systems,
you need to rename these files to the `.doc` extension, after processing.

1. Enter a variable component on the design canvas that stores the file path with extension.
2. Add the ChangeExtension action after the variable component.
3. Set the target extension to `.pdf`.
