Jspreadsheet
Jspreadsheet is a JavaScript spreadsheet component you drop into web apps when users expect Excel behavior, not just a sortable table. It ships as a front-end library for vanilla JavaScript, React, Vue, or Angular, with 500+ Excel-compatible formulas, import and export for 16+ file formats, and optional AI functions wired into cells. Because the code runs in your application, data stays on your infrastructure under your security model.
Most data grid libraries optimize for read-heavy tables with filtering and pagination. Jspreadsheet targets the opposite workload: modeling, bulk edits, and reporting where the fill handle, absolute references, and paste-from-Excel round-trips are what users test in the first minute. Google Sheets and Excel bake AI into their clouds; Jspreadsheet ships code so you choose the model endpoint, including a local one with no outbound traffic.
It fits teams building SaaS products, internal tools, financial dashboards, and data entry screens that still revolve around spreadsheets. Customer logos on the site include Samsung, Deloitte, and Johnson & Johnson. Jspreadsheet Server adds an optional Node.js backend for live multi-user editing, version history, and document persistence when a browser-only component is not enough.
