    ChangeExtension component

    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.
