API Reference

The classes, interfaces, and functions you use to build with SheetXL: create and calculate workbooks, load and save spreadsheet files, and embed the spreadsheet UI in a React app.

Where to start

• @sheetxl/sdk is the primary API: workbooks, sheets, ranges, and calculation. Most code only needs this.
• @sheetxl/primitives holds the low-level types (Scalar, IRange) that the SDK and custom functions share.
• @sheetxl/io loads and saves workbooks.
• @sheetxl/studio-mui is the complete spreadsheet UI as a React component.
