Details​

Charts​

xlmake is designed for data export, so chart functionality is not supported. If you need charts, consider generating them as images and inserting with .image().

Formulas​

xlmake does not support formulas. Perform calculations in JavaScript/TypeScript and pass the results as data.

// NG: Formulas don't work
// { total: "=A1+B1" }

// OK: Pass calculated results
{ total: price + quantity }

Appending to Existing Excel​

xlmake always generates new Excel files. Appending to existing files is not supported.

Column Width/Row Height Reading​

When reading existing Excel files with read(), column width and row height information cannot be retrieved.

Pivot Tables / Macros​

xlmake is designed for simple data export, so pivot tables and macros are not supported.

Alternatives​

For more advanced Excel operations, consider using ExcelJS directly. xlmake is built on ExcelJS but focuses on providing a more declarative and user-friendly API.
