ONLYOFFICE Spreadsheet Versions and Free Desktop Access

Quick answer: The spreadsheet editor is included in free ONLYOFFICE Desktop Editors for Windows, macOS and Linux. Use the official desktop download page to select your operating system and processor. Local desktop editing is a different setup from a hosted collaborative service or an organization’s server deployment.

Checked October 20, 2026. These are documented release and availability details. We did not install the software, connect a cloud account, execute a workbook or capture native screenshots for this reference.

Which release is currently documented?

The official download page lists 10.0.0, dated October 13, 2026, for the principal desktop downloads. The desktop changelog independently lists that release. This is a dated observation, not a guarantee that 10.0.0 remains the newest installer.

The changelog describes a rebuilt application and warns that some earlier settings cannot transfer. Cloud connections may require signing in again, and a custom username may need to be entered again. Treat an upgrade as a change worth testing on disposable files, not a reason to overwrite your only working copy.

Do not confuse a legacy download offered for an older operating system with the main current release. Also avoid applying the desktop release number to the mobile apps or to a server: they have their own update histories.

Free packages and platform scope

The download page provides Windows architecture choices, Intel and Apple-chip macOS choices, and multiple Linux package formats and architectures. Choose the package that matches the actual machine. Separate legacy operating-system links are not a recommendation to keep using an unsupported operating system.

The getting-started guide identifies Desktop Editors as open-source software under AGPL v3 and describes working on local files without a constant internet connection. Its local spreadsheet workflow is the free route covered here.

Cloud connections add online and collaborative capabilities. Their availability depends on the particular service or deployment; the existence of a free desktop download does not make every hosting plan, server offering or AI integration free. This page does not require a cloud subscription, API key, paid trial or AI configuration.

Record the application you actually use

Record the installed desktop version, operating system, architecture and package source before following version-specific instructions. The getting-started guide describes update choices in Settings and Check for updates in the About section. If a Linux package is managed by a distribution, record that package source as well when comparing it with the upstream release.

A screenshot in documentation may come from an earlier interface. Use the version and written instructions together rather than assuming every pictured button proves the appearance of the current release.

A small local-file smoke check

This proposed manual check has independently calculated results; we did not execute it in ONLYOFFICE:

1. Create a disposable blank spreadsheet. Enter 12 in B2 and 18 in B3.
2. Enter =SUM(B2:B3) in B4. The expected total is 30.
3. Replace B3 with 20. B4 should show 32.
4. Save the disposable file as XLSX in a known local folder. Close it, reopen it and check the formula and results.

The official guide describes choosing a filename, format and location when saving. It lists XLSX, ODS and CSV among supported spreadsheet formats, but supported formats are not a promise of identical features. Keep the XLSX test file when experimenting with another format; a CSV copy is not an equivalent multi-sheet workbook.

If a result differs, record the exact formula, visible error and installed version before investigating. This small check cannot validate macros, complex charts, external connections or every Excel conversion. Continue with the SUM guide, ONLYOFFICE tutorials or the ONLYOFFICE hub.
