I am wondering if any way to export the CouchDb query-view to .csv as can be done in mongodb.
CouchDB does not natively support CSV exports, however the CHT API has some export functions that return CSVs. What were you trying to export?
For CouchDB questions you can get more specific support on their mailing list or Slack linked from the CouchDB main website.
Thank you @gareth will check in over this and expect to discuss further over this.
