XLibur

About

XLibur is a .NET library for reading, manipulating and writing Excel 2007+ (.xlsx, .xlsm) files. It aims to provide an intuitive and user-friendly interface to dealing with the underlying OpenXML API.

This is a fork from the ClosedXML project, taken from version v0.105.0 (May 15, 2025). Namespaces are changed to avoid conflicts with the original project.

Primary differences from ClosedXML (0.105)

  • Dropped support for <net8
  • Enable nullability annotations.
  • Leverage later C# lang features.
  • Fix some outstanding bugs we wanted.
  • Improve memory usage, especially with formatted cells.

Migration from ClosedXML

At present most of the surface area is the same as ClosedXML. Import the NuGet package, rename the namespace to XLibur, and in most cases you should be ready to go.

Install

dotnet add package XLibur

What can you do with this?

XLibur allows you to create Excel files without the Excel application. The typical example is creating Excel reports on a web server.

Example:

using (var workbook = new XLWorkbook())
{
    var worksheet = workbook.Worksheets.Add("Sample Sheet");
    worksheet.Cell("A1").Value = "Hello World!";
    worksheet.Cell("A2").FormulaA1 = "=MID(A1, 7, 5)";
    workbook.SaveAs("HelloWorld.xlsx");
}
