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.

Install

The recommended package is XLibur.Bundle, which installs the core library together with the default font engine and behaves like ClosedXML out of the box:

dotnet add package XLibur.Bundle

Or via the Package Manager console:

PM> Install-Package XLibur.Bundle

Quick start

XLibur lets you create and manipulate Excel files without Excel installed — a common use case is generating reports on a web server.

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");
}

More in the Getting Started guide.

Ancestry

XLibur forked ClosedXML v0.105. Namespaces are prefixed with XLibur. Surface API is mostly compatible, but check the docs for details.

Migration from ClosedXML

The public API surface is largely unchanged from ClosedXML 0.105. To migrate:

  1. Install XLibur.Bundle (see Install)
  2. Replace using ClosedXML namespace references with using XLibur

One behavioural difference: font engines. ClosedXML bundles SixLabors.Fonts into its core assembly for text measurement (column auto-fit, row heights, glyph metrics). XLibur keeps the core assembly free of any font library and ships the font engine as a separate, swappable package, so you can pick one whose license suits you.

With XLibur.Bundle, no code changes are needed — the SkiaSharp engine (MIT) auto-registers the first time you create a workbook, and falls back to an embedded metric-only Calibri-compatible font so measurement works in headless environments. Installing the bare XLibur package with no font engine throws an InvalidOperationException on workbook creation telling you which package to add.

To use a different engine — including SixLabors 1.x, which matches ClosedXML 0.105's behaviour exactly — see docs/font-architecture.md for the available packages, their licenses, and the engine resolution order.

Report templating

XLibur.Report generates reports from .xlsx templates: author the report in Excel, bind .NET data to it, and generate the finished workbook. Charts, pivot tables and pictures survive range expansion, which is the part comparable libraries do not do.

using var template = new XLTemplate("SalesReport.xlsx");
template.AddVariable("Company", "Contoso");
template.AddVariable("Sales", sales);
template.Generate();
template.SaveAs("SalesReport-2026.xlsx");

XLibur.Bundle

See release notes https://github.com/XLibur/XLibur/releases/tag/v0.730.1-beta.1 Convenience meta-package for XLibur. Installs XLibur together with the default SkiaSharp font engine (MIT). The engine auto-registers on first use — no startup call required. Equivalent to installing XLibur and XLibur.Fonts.SkiaSharp separately.
XLibur.Fonts.SixLabors.V1

See release notes https://github.com/XLibur/XLibur/releases/tag/v0.730.0 Default IXLFontEngine implementation for XLibur using SixLabors.Fonts 1.x (Apache 2.0).
XLibur.Fonts.SkiaSharp

See release notes https://github.com/XLibur/XLibur/releases/tag/v0.730.1-beta.1 SkiaSharp implementation of IXLFontEngine for XLibur.
XLibur.Fonts.SixLabors

See release notes https://github.com/XLibur/XLibur/releases/tag/v0.730.1-beta.1 SixLabors.Fonts 2.x implementation of IXLFontEngine for XLibur.
XLibur.Report

See release notes https://github.com/XLibur/XLibur/releases/tag/report-v0.620.0 Report templating for XLibur. Author a report as an ordinary .xlsx template — placeholder expressions, named ranges and tag markers — bind .NET data to it, and generate the finished workbook. Charts, pivot tables and pictures survive range expansion.
