Our Ecosystem
SheetXL is layered so you can use the complete studio or compose exactly what your application needs.
Each package has a single clear purpose and works independently or as part of the full stack.
Package names link to their API reference where one is published.
Core
A fully embeddable spreadsheet engine and API. Think Office Scripts meets NumPy: a complete workbook model, vectorized calculations, and scripting, without the server.
| Package | Description | License |
|---|---|---|
| @sheetxl/sdk | High-performance headless spreadsheet engine with a full workbook API, calculation pipeline, and scripting support. | Commercial |
| @sheetxl/primitives | Core TypeScript interfaces and types (Scalar, IRange) shared by the SDK and by functions. | MIT |
Formulas
The function libraries the engine calculates with.
| Package | Description | License |
|---|---|---|
| @sheetxl/formulas | The Excel-compatible built-in function library, authored using the same public API as UDFs, making them a clean reference for writing your own. | MIT |
| @sheetxl/formulas-extended | Specialist financial modeling and statistical forecasting functions. | Commercial |
UI
Ready-to-use components for embedding spreadsheets in your application.
| Package | Description | License |
|---|---|---|
| @sheetxl/studio-mui | Complete spreadsheet application delivered as a React component using Material-UI. Embed a full spreadsheet in minutes. | MIT |
| @sheetxl/studio-vanilla | Plain JavaScript wrapper around Studio-MUI for integration into non-React applications. | MIT |
| @sheetxl/react | Core React spreadsheet components used by Studio-MUI (cells, sheets, toolbars, dialogs). | Commercial |
| @sheetxl/grid-react | Virtualized React grid with a layer-based architecture. Compose selection, editing, tooltips, and custom overlays as React components. | Commercial |
All UI packages are built entirely on the public @sheetxl/sdk API. Nothing is hardwired. Anything the built-in UI can do, your code can do too.
I/O
Read and write workbooks in different formats.
| Package | Description | License |
|---|---|---|
| @sheetxl/io | Import and export workbooks in SXL, JSON, and CSV formats. | MIT |

Scripting
Extend SheetXL with custom functions and automation, and give your users an editor to write them in.
| Package | Description | License |
|---|---|---|
| @sheetxl/scripting | TypeScript/JavaScript compilation engine for authoring macros and user-defined functions (UDFs). | Commercial |
| @sheetxl/scripting-react | Monaco-based script editor and scripting UI for React. | Commercial |

Tooling
Operate SheetXL from the terminal.
