ONLYOFFICE or Collabora?

ONLYOFFICE if you want the AGPL OOXML suite. Collabora if you want the MPL LibreOffice-based editor (the Nextcloud Office wrap). /compare/onlyoffice-vs-collabora.

Is this Google Sheets?

A .xlsx file, yes. A live multiplayer sheet with relations is Grist — /replace/google-sheets.

Why not just Nextcloud?

Nextcloud is the Drive suite that can wrap these editors — /replace/google-drive. This page is the editor itself.

ONLYOFFICE / Collabora

An office suite you host. ONLYOFFICE Docs is AGPL-3.0; Collabora Online is MPL — Word, Excel, PowerPoint, and Google Slides without the Microsoft 365 or Workspace seat.

The problem

Microsoft Word, Excel, and PowerPoint are the Microsoft 365 editors. Google Slides is the Workspace deck. You wanted .docx/.xlsx/.pptx on hardware you control. ONLYOFFICE Document Server is AGPL-3.0 (ONLYOFFICE/DocumentServer). Collabora Online is MPL (already named on /replace/google-docs). CryptPad is AGPL-3.0 if the job is an end-to-end-encrypted pad, not an OOXML suite. This is not Microsoft 365 Copilot, Excel's every Power Query SKU, or Google Slides' add-on store. A live sheet with relations stays on /replace/google-sheets (Grist). Files-and-suite Nextcloud stays on /replace/google-drive.
