Converter: CLOB to String

### Use case

I'm working with an Oracle database, and when executing a query that returns a CLOB (Character Large Object) containing a JSON request body, I need to convert the CLOB to a string. This is crucial for comparing it with the executed API request body. I would greatly appreciate a JSR233 function or script that effectively handles this CLOB conversion in JMeter.

### Possible solution

some kind of reader that convert the clob into a string.
