Limitations and Usage

Constraints and ideal use cases

SpreadJS covers a wide range of Excel features; some high-end options (e.g. macro/VBA, Power Query) are not built-in, and the Designer ribbon, PivotTable, and Gantt are separate modules. License is per developer and per hostname; renewal is required for updates. Jspreadsheet Community has some Pro extensions gated; Enterprise unlocks full spreadsheet and collaboration. Choose Jspreadsheet for a lightweight, collaboration-ready option with site-wide licensing; choose SpreadJS if you need maximum Excel parity and optional add-ons (Pivot, Designer, Gantt) from a single vendor.

"At SplitC we struggled sometimes when users wanted to bulk insert/edit things (sometimes over 100k rows) and we needed performance. Jspreadsheet is probably the fastest spreadsheet component you'll find out there, and with a small bundle size. By the way, support is awesome."
