OnlyOffice

ONLYOFFICE connector allows you to view, edit and collaborate on text documents, spreadsheets and presentations within Nextcloud using ONLYOFFICE Docs. This will create a new Edit in ONLYOFFICE action within the document library for Office documents. This allows multiple users to co-author documents in real time from the familiar web interface and save the changes back to your file storage.
