Welcome to the ONLYOFFICE stand


In 2020, we made lots of useful enhancements in all ONLYOFFICE solutions.
More efficient collaboration:
  • Custom filter access permission that allows hiding the data you don’t want to show before sharing your spreadsheet.
  • Sheet View option that allows creating a filter that only changes your view of the data, without affecting your collaborators.
  • Document comparison that allows quickly comparing two docs and see differences between them with revision marks, accept/reject/merge the changes.
New productivity features in ONLYOFFICE Docs:
  • Pivot tables, conditional formatting for viewing, slicers for formatted tables in spreadsheets.
  • Mirror and gutter margins, endnotes and cross-references in docs.
  • New plugins Zotero, Mendeley, Autocomplete, Telegram, HTML, Word Count, Typograf.
New security features:
  • Storage encryption at rest.
  • The first version of Private Rooms which are protected workplaces where every symbol you type is encrypted using the unbreakable AES-256 algorithm, even if you are co-editing documents with your teammates in real-time.
Product portfolio changes:
ONLYOFFICE Groups released under Apache 2.0 what allows modifying and distributing it without limitations. It can be easily deployed in a few steps and integrated into any product ecosystem.
  • Multiple enhancements for the existing integrations, especially with Nextcloud and ownCloud.
  • New connectors for HumHub, Plone, and Nuxeo.
For now, we’re working on multi-functional forms that will allow quickly building any complex document template online.
