Euro-Office Launches 1.0 as TDF Attacks OOXML Default and 'First European' Claim
2 articles · Updated · ZDNet · Jun 11
Summary
June 9 brought Euro-Office 1.0, the first stable release of a browser-based office suite pitched as an EU digital-sovereignty alternative to Microsoft 365 and Google Workspace.
TDF challenged that pitch in a June 7 open letter, saying Euro-Office's default use of Microsoft's OOXML format undercuts sovereignty and that compatibility with Office files should not replace ODF as the native standard.
The foundation also rejected Euro-Office's claim to be the first European open-source office suite, pointing to OpenOffice.org and LibreOffice as earlier Europe-rooted predecessors.
Backers including Nextcloud and Ionos say the fork shifts governance, hosting and legal control to Europe, while ODF support remains on the roadmap and packaged deployments are already available.
The release still looks more like a tech preview than a production-ready suite, highlighting how Europe's sovereignty push is colliding with open-source rivalry and entrenched Microsoft document formats.
Is Euro-Office a real path to digital freedom, or a surrender to Microsoft’s standards disguised as sovereignty?
With Nextcloud backing two rival office suites, which one offers a genuine escape from Big Tech for European users?

Overview
Euro-Office 1.0, launched on June 9, 2026, is a new open-source, web-based office suite created as a European alternative to US-based platforms. The project is driven by the goal of European sovereignty, aiming to give users more control over their data and reduce reliance on non-European cloud providers. Backed by a coalition of European tech companies, Euro-Office aligns with EU objectives for digital autonomy and local data residency. Its launch marks a strategic move to address concerns about data protection and to provide a trustworthy, European-governed solution for public sector and enterprise users.
