Oracle Database schema validation

I am working on a database migration and want to validate the destination schema against the source schema for Tables, Views, Indexes, Sequences, Constraints etc. I can do that by querying the dba_ tables individually. This is time consuming and we have to record the results manually I was wondering if there is any pl/sql code which can be used to perform all these validations at once and give an output which can be stored in a CSV/excel
