Search for "Replace pattern" or find the operation under "Preprocessing & cleaning" and click it.



2. Name the output text field

Under "Output field name", type the name of the output text field.

3. Define the pattern to replace

Click "Apply" to run the operation. A new field containing the output text, where the pattern has been replaced, has now been added.
