SpreadsheetPreview

The product is a browser-based component that renders view-only previews of Excel XLSX workbooks without uploading files to a server or requiring Microsoft Office. It solves the problem of displaying spreadsheets inside web applications with fidelity for sheets, formatting, and layout. It is sold to developers and product teams building SaaS products, portals, and enterprise tools. It is positioned as a client-side alternative to server-side conversion and Office automation, running entirely in the browser via a constructor API or Web Component.
