You can use the js provided in a JavaScript box in Composer, with modifications for the context. Another option is to use formulas, e.g. REPLACE_ONE_REGEX might work, or perhaps SPLIT together with MAP or similar. If you can describe your use case, perhaps I can help you further :slight_smile:

Thanks @Mari . I already made it using javascript code above. after hours of playing around. thanks for responding.
