Topic	XiKey Sheet	Microsoft Excel
Price and availability Source 1 ↗Source 2 ↗	Planned/unreleased Alpha product. Alpha policy is free; Beta XiOffice bundle is listed at US$29/year for XiKey Write, XiKey Sheet and XiKey Slides, before tax.	Microsoft 365 Personal is US$99.99/year for one person and includes several apps and cloud storage. This is a bundle price, not Excel alone.
Workbook exchange Source ↗	Upstream reads/writes XLSX and imports limited XLS/XLSB/ODS data. Some advanced content is not preserved; XiKey release validation is pending.	Excel supports its workbook, macro-enabled, binary and legacy workbook formats. Conversion to other formats can also lose features.
External data Source ↗	Upstream offers local files and worksheet tools; the Power Query editor, refresh and data-model workflow are documented gaps.	Power Query connects, transforms, combines and refreshes external sources; capabilities differ by platform.
Working together Source ↗	No verified XiKey live co-authoring. The upstream documents co-authoring and cloud storage as gaps; comments are not a shared editing service.	Supported Excel versions can co-author workbooks stored in OneDrive or SharePoint Online.
Arabic workflow Source ↗	Arabic UI, one-click EN ⇄ ع, style-grouped fonts and Arabic office text tools are in progress. Do not assume Arabic PDF fidelity today.	Office documents Arabic and right-to-left editing support, with language and keyboard setup.
Automation ecosystem Source ↗	Upstream exposes CLI and MCP commands. VBA execution and Office Scripts compatibility are not established; XiKey Launcher add-ons are planned.	Desktop Excel exposes a documented VBA object model for automating workbook tasks.

Where the other product is stronger

Excel is the stronger current choice for live collaboration and connected-data workflows: https://support.microsoft.com/en-us/excel/about-power-query-in-excel; https://support.microsoft.com/en-us/excel/get-started/collaborate-on-excel-workbooks-at-the-same-time-with-co-authoring (checked 2026-10-14).
Excel supports its established macro and workbook workflows; XiKey Sheet has no verified release and the upstream still documents compatibility and calculation limits: https://support.microsoft.com/en-us/excel/file-formats-that-are-supported-in-excel; /products/xisheet/#open-source-components.
Existing VBA automation can remain in Excel; XiKey Sheet is not a drop-in VBA replacement: https://learn.microsoft.com/en-us/office/vba/library-reference/concepts/getting-started-with-vba-in-office/; /products/xisheet/#open-source-components (checked 2026-10-14).
