|---|---|---|
| Free Version | MIT Community Edition for non-commercial use; 30-day free trial for evaluation | No free plan for production; 30-day trial only |
| Paid Plans | $1,999/year (Enterprise for teams of 5 or fewer developers) | ~$1,499/year per developer (one hostname, one year support) |

Technical Features
Performance, API, and data handling
Both are client-side spreadsheet components with React, Vue, and Angular support. SpreadJS uses a C++/WASM calculation engine for fast recalculation and can handle large sheets. Jspreadsheet uses a small bundle and virtual rendering for 100k+ rows, with lower memory usage and built-in XLSX and Google Sheets import/export.
| Feature | Jspreadsheet | SpreadJS |
|---|---|---|
| Infrastructure | Browser-based; self-hosted or embedded | Client-side; optional server components for import/export |
| Framework Support | ✓ React, Vue, Angular wrappers | ✓ React, Vue, Angular |
| File Import/Export | Built-in JSON, CSV, XLSX + Google Sheets importer | Excel .xlsx (client or server), JSON, CSV, PDF |
| Bundle Size | 85 KB | 2.73 MB |
| Memory Usage | 222 KB | 2.54 MB |
| Large Data | ✓ Virtual rendering for 100k+ rows | ✓ 1M+ cells (WASM calc engine) |
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.
| Aspect | Jspreadsheet | SpreadJS |
|---|---|---|
| Row/Column Limits | No hard limits; 100k+ rows with virtualization | 1M+ cells; browser memory is main limit |
| Feature Limitations | Advanced features (500+ functions, collaboration) in Pro/Enterprise | Ribbon UI, PivotTable, Gantt are separate add-ons; no built-in collaboration |
| Best For | Lightweight embedding Formulas & collaboration Site-wide team licensing | Maximum Excel parity Enterprise reporting Optional Pivot/Designer add-ons |
