OpenExcelLite

A lightweight, schema-safe Excel (XLSX) generator for .NET using the official OpenXML SDK.
Supports both in-memory and streaming Excel creation β€” designed for fast, dependency-free exports.

✨ Features

  • In-memory Excel builder
  • Streaming XLSX writer for large datasets (100k–1M rows)
  • Table creation with styling
  • AutoFilter support
  • AutoFit column widths (approx algorithm)
  • Date formatting (OADate + style index)
  • Automatic header validation and deduplication
  • Boolean, numeric, string inference
  • NEW in v1.1.0: Blank row support (in-memory + streaming)

πŸš€ New in v1.1.0 β€” Blank Row Enhancements

βœ” AddEmptyRows() β€” In-Memory Builder

s.AddEmptyRows(3);
s.AddRow("Id", "Name");
s.AddRow(1, "Alex");

βœ” Streaming: WriteEmptyRows()

writer.WriteEmptyRows(5);
writer.WriteRow("Id", "Name");

βœ” Improved Stability

  • Table ranges compute correct header-row offset
  • AutoFilter respects actual header row
  • Eliminates Excel β€œRepaired Records” warnings
  • Fully compliant with ECMA-376 schema

πŸ“„ Example (In-Memory)

var bytes = new WorkbookBuilder()
    .AddSheet("Demo", s =>
    {
        s.AddEmptyRows(2);
        s.AddRow("Id", "Name", "Active");
        s.AddRow(1, "Alex", true);
        s.AddRow(2, "Brian", false);
        s.AddTable("Employees");
    })
    .Build();

File.WriteAllBytes("demo.xlsx", bytes);

πŸ“„ Example (Streaming)

var bytes = StreamingWorkbookBuilder.Build("Demo", writer =>
{
    writer.WriteEmptyRows(4);
    writer.WriteRow("Id", "Name");
    writer.WriteRow(1, "Alex");
});
