WorksheetJS vs AG Grid
An AG Grid alternative for when you need a real spreadsheet, not just a grid.
Last updated 2026-06-15 · pricing as of June 2026
AG Grid is the industry-leading data grid; WorksheetJS is a full spreadsheet engine. They overlap on “editable table in the browser” but solve different problems. AG Grid excels at displaying, sorting, filtering, and editing large datasets with enterprise grid features. WorksheetJS adds what a grid isn't built for: a 550+ function Excel-compatible calculation engine, an AI copilot, charts, pivot tables, and full-fidelity XLSX round-tripping — an actual spreadsheet your users recognize. AG Grid Community is free (MIT); Enterprise is $999/dev perpetual or roughly $995–1,295/dev/yr. WorksheetJS starts with a free dev tier and at $14.99/mo.

Key differences explained
Two different categories
AG Grid is built to display, sort, filter, and edit large datasets with enterprise grid features like the server-side row model. WorksheetJS is built to be a spreadsheet: formulas, multi-sheet workbooks, pivots, and XLSX round-trip. Picking the right category up front avoids forcing one tool to do the other's job.
Calculation engine and workbooks
AG Grid has no native Excel formula engine or multi-sheet workbook model — that isn't its purpose. WorksheetJS provides 550+ formulas and full workbook semantics, so end users get recalculation, references across sheets, and familiar spreadsheet behavior out of the box.
Charts, pricing, and the free tier
WorksheetJS bundles charts; AG Grid's charting is a separate product (AG Charts). AG Grid's Community edition is free under MIT, with Enterprise from $999/developer; WorksheetJS offers a free developer tier and paid plans from $14.99/mo (as of June 2026). Choose by whether you need a grid or a spreadsheet, not by price alone.
Where each one wins
Where WorksheetJS wins
- It's a spreadsheet, not just a grid: real formulas, multi-sheet workbooks, pivots, charts, XLSX.
- Native AI copilot — AG Grid has no built-in AI.
- Charts are bundled (AG Grid's charting is a separate product).
Where AG Grid wins
- The gold standard for data grids — column groups, advanced filtering, server-side row model.
- Free Community tier under MIT for pure grid needs.
- Enormous adoption, ecosystem, and hiring pool.
Best for
Choose WorksheetJS if you're when users expect an actual spreadsheet (formulas, sheets, pivots, charts) or you want AI built in.
Choose AG Grid for when you need a powerful virtualized data grid and not a spreadsheet calculation engine.
Migrating from AG Grid
If you adopted AG Grid for grid features but users keep asking for 'real spreadsheet' behavior, you can add WorksheetJS for those surfaces rather than rebuilding — the two coexist well, with AG Grid handling operational tables and WorksheetJS handling spreadsheet workflows.
