How to find whitespace in subdocument and trim the spaces?

Working with Data

Is there any way to do this: I have a requirement to identify subdocument which has whitespace (leading and/or trailing) as shown below. Once the query identifies the record, I want to trim its spaces and update the record.

Expected output: Query should return only first subdocument where name and key has whitespaces.
