xlsxwriter library

A native, fast, low-memory Excel .xlsx writer for Dart.

This library is an FFI binding to libxlsxwriter by John McNamara, compiled from vendored C source at build time. It targets the report- and export-generation use case: writing spreadsheets quickly and with low memory. It does not read existing files; for that use the excel or spreadsheet_decoder packages.

import 'package:xlsxwriter/xlsxwriter.dart';

void main() {
  final workbook = Workbook('report.xlsx');
  final sheet = workbook.addWorksheet('Summary');
  final header = workbook.addFormat()..bold();
  sheet.writeString(0, 0, 'Item', header);
  sheet.writeString(0, 1, 'Amount', header);
  sheet.writeString(1, 0, 'Widgets');
  sheet.writeNumber(1, 1, 1250);
  workbook.close();
}
