If your BSON exists within MongoDB, Assure and Data360 Analyze are able to read it directly from Mongo. They wouldn't be able to read extracted (standalone) BSON outside of MongoDB.
For compressed data, Assure and Analyze can read zip files. Just to include the sources here too, information on capturing zips can be found in these community posts for Assure and Analyze.
Depending on what you want to classify as compressed, Assure, Analyze and DQ+ can read from Excel files, which are technically zip-based. Data360 DQ+ can also read from various compressed Hadoop file types, such as parquet and ORC.
