Redesigned interface makes editing modern again

One of the most useful additions is the new Diagram Viewer, which eliminates the need to use a third-party app to open diagram files. Available on the web, desktop, and mobile, the app supports formats like Visio (.vsd, .vsdx) and OpenDocument Graphics (.odg).

Whether you're reviewing organizational charts, flowcharts, or engineering diagrams, this integrated viewer streamlines the process of opening and examining images on any device.

Markdown support and network compatible extension formats

ONLYOFFICE Docs 9.0 enhances cross-platform and multi-format usability by adding support for Markdown (.md) files. This is a welcome update for developers, writers, and anyone working in plain text environments.

Other additions include editable Excel Binary Workbooks (.xlsb), enhanced support for Visio files, and broader compatibility with open document formats. These improvements make the platform more flexible for professionals managing a wide variety of document types.

Docs 9.0 doesn't just look great—it helps you work smarter. New AI-powered features bring automation to the forefront of the suite, especially in spreadsheets and macros. These tools are designed to simplify workflows that often require manual effort.

In spreadsheets, AI now helps users apply formulas, analyze data trends, and uncover insights faster. Macro Assistant benefits from AI-assisted creation and VBA conversion, allowing users to build automated workflows without having to dive into programming. For teams dealing with large data sets or routine calculations, these features can significantly cut down on tedious work.

Intelligent PDF tools deliver real-time collaboration and advanced editing

The PDF editor also gets a significant upgrade in this release. Users can now co-author PDF forms in real time, allowing teams to fill out or design forms together. This collaborative form editor is especially useful for tax documents, HR paperwork, and legal agreements that require multiple people to input data.

Docs 9.0 also introduces drag-and-drop page reordering via thumbnails and shortcut-based page duplication, allowing for more flexible document structure. Combined, these features make working with PDFs almost as seamless as editing a Word document.

Edit documents and presentations more powerfully than ever

The Document Editor now allows users to apply paragraph borders with a single click from the toolbar. Content Controls have been improved to support visual tracking of changes and plugin-based custom buttons, expanding interactivity and visibility.

Presentation creators will see that Docs 9.0 introduces support for paragraph navigation controls—ideal for RTL languages—and more advanced text animations that appear correctly in slideshow mode. This gives presenters more flexibility in multilingual environments and helps deliver better visuals.

Localization updates and RTL improvements support global audiences

True to its open source roots, ONLYOFFICE continues to prioritize accessibility and localization. Docs 9.0 includes right-to-left (RTL) text improvements for languages like Arabic and Hebrew. Users can now set paragraph direction from the toolbar, enjoy better cursor navigation, and experience accurate border rendering in RTL layouts.

New language support includes Urdu and additional Arabic spell checkers, along with enhanced font settings in the Simplified Chinese interface. Server admins can now also upload custom dictionaries, further tailoring the editing experience to the specific needs of their organization.

Smart charts and better data control for all editors

Across all editors, charting tools are more powerful with new options like Up/Down bars and stylized WordArt annotations. These features help create visually appealing charts that communicate data more clearly.

Spreadsheet users benefit from support for asynchronous calculations, allowing complex custom functions to run more efficiently. There's also a new option to pull data from external spreadsheets, making Docs 9.0 a more lightweight data integration tool.

Mobile and desktop applications

ONLYOFFICE hasn't left mobile and desktop users behind. The iOS and Android mobile apps now support opening Markdown files and include AI-powered text recognition in images, giving users more freedom to work on the go.

Desktop editors also get access to new features, including AI support, diagram viewing, and a redesigned interface. Whether self-hosted or deployed across desktop and mobile, Docs 9.0 is all about consistency across platforms.

Available now for self-hosting, with cloud updates to follow

ONLYOFFICE Docs 9.0 is now available as a self-hosted package for organizations and users who prefer to run the software on their own infrastructure. For those using cloud-based deployments, the update will be rolling out soon. This approach gives businesses and privacy-conscious users more control over when and how new features are applied.

Docs 9.0 proves that ONLYOFFICE is serious about becoming the go-to productivity suite. By combining beautiful design, extensibility, collaborative workflows, and intelligent automation, the platform offers a compelling alternative to traditional office software.

For professionals looking for a powerful, flexible, and open-source suite of tools for editing documents, spreadsheets, presentations, and PDFs, this latest update is a good reason to reconsider ONLYOFFICE.
