EPPlus-LGPL 4.5.3.13

EPPlus-LGPL

EPPlus-LGPL is an unofficial EPPlus library which includes bug fixes beyond EPPlus 4.5.3.3 while retaining a LGPL license, such as support for .NET 8. (The official version of EPPlus v5+ is not available for commercial use without acquiring a license.)

.NET 6+ support on Linux

All features are available on Windows. However, System.Drawing.Common support on Linux is deprecated on .NET 6 and removed from .NET 7 and .NET 8. This library currently relies on its support for the following features:

• Adding images
• Setting fonts via the Font class

So long as you do not use these features, you can use this library on .NET 6+ on Linux. Note that you can set fonts by setting the individual font properties such as Name, Bold, Italic, Size, and so on.

To use these features on prior versions of .NET Core running on Linux, you will need to install the libgdiplus package. For example, on Ubuntu, you can run sudo apt install libgdiplus to install it.

To use these features on .NET 6 running on Linux, you must add the below to your project file.

<ItemGroup>
  <RuntimeHostConfigurationOption Include="System.Drawing.EnableUnixSupport" Value="true" />
</ItemGroup>

For more information, visit https://learn.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/6.0/system-drawing-common-windows-only

Please note that the auto-sizing columns feature uses font metrics collected from a Windows PC, and may not carry metrics for the fonts you use.

About EPPlus

Create advanced Excel spreadsheets using .NET, without the need of interop.

EPPlus is a .NET library that reads and writes Excel files using the Office Open XML format (xlsx). EPPlus has no dependencies other than .NET.  

EPPlus supports:

• Cell Ranges
• Cell styling (Border, Color, Fill, Font, Number, Alignments)
• Data validation
• Conditional formatting
• Charts
• Pictures
• Shapes
• Comments
• Tables
• Pivot tables
• Protection
• Encryption
• VBA
• Formula calculation
• Many more...

Overview

This project started with the source from ExcelPackage. It was a great project to start from. It had the basic functionality needed to read and write a spreadsheet.

Advantages over other:

• EPPlus uses dictionaries to access cell data, making performance a lot better.
• Complete integration with .NET

New features in version 4.5

• .NET Core support
• Sparklines
• Sort method added to ExcelRange
• Bug fixes and minor changes, see below and visit https://github.com/JanKallman/EPPlus for tutorials, samples and the latest information

Important Notes:

• Breaking change in .NET Core: The Worksheets collection will be zero based as default.
• This can be altered by setting the ExcelPackage.Compatibility.IsWorksheets1Based to true.
• .NET Core will have this property set to false, and .Net 3.5 and .Net 4 version will have this property set to true for backward compatibility reasons.
• This property can also be set via the appsettings.json file in .Net Core or the app.config file. See sample project for examples!

.NET Core uses a preview of System.Drawing.Common, so be aware of that. We will update it as Microsoft releases newer versions. System.Drawing.Common requires libgdiplus to be installed on non-Windows operating systems. Use your favorite package manager to install it. For example:

Homebrew on MacOS:

brew install mono-libgdiplus

apt-get:

apt-get install libgdiplus
