Sheets covers spreadsheets and embeddable calculation grids. Proprietary sheet clouds turn formulas, named ranges, and sharing links into a retention graph. FLOSS engines and LibreOffice-based online stacks keep calculation closer to hardware and formats you control.

Browse the NGI-funded projects below.

These tools are not all NGI grants, but they are what people actually run for calculation without a Google Sheets or Excel 365 account.

	IronCalc is an embeddable spreadsheet engine in Rust — formulas and grids you can host without a Microsoft or Google sheet account.
	Collabora Online brings LibreOffice into the browser for collaborative documents, sheets, and slides — with visual search improvements under the NGI grant.
	CryptPad adds secure surveys and polls on top of CryptPad’s end-to-end encrypted pads, sheets, and kanban — data stays ciphertext on the server.
	ZetaOffice runs collaborative LibreOffice editing client-side in the browser with end-to-end encryption — the grant formerly linked as LibreOffice P2P.
	LibreOffice remains the full desktop suite in the commons: Writer, Calc, Impress, and related tools on the OpenDocument Format — the practical fallback many organisations can install today.
