poi-ikvm-net

Enables the use of Apache POI 5.2.5 in .NET applications (.NET 9 and above) by using IKVM to compile Java to .NET.

This package allows you to read, write, and manipulate Microsoft Excel files natively within your .NET applications, exposing identical Java namespaces (org.apache.poi.*).

Features

  • .NET Target: Targets .NET 9. For .NET Framework use poi-ikvm
  • Up-to-Date POI: Targets Apache POI 5.2.5 which is the last version to support Java 8 enabling use with IKVM
  • Self-Contained: All transpiled Maven dependencies (such as XMLBeans, Commons-Compress, Commons-Math, etc.) are bundled directly inside the package. No external JDK required!
  • Identical Namespaces: Keeps namespaces identical to original Java Apache POI

Installation

Install the package via the .NET CLI:

dotnet add package poi-ikvm-net

Or via the Package Manager Console:

Install-Package poi-ikvm-net

Quick Start Example (C#)

The following example demonstrates how to create a new Excel workbook, add a sheet, write a value to a cell, and save it to a file:

using System;
using org.apache.poi.xssf.usermodel;

try
{
    Console.WriteLine("Creating workbook...");
    using var workbook = new XSSFWorkbook();
    var sheet = workbook.createSheet("Sheet1");
    var row = sheet.createRow(0);
    var cell = row.createCell(0);
    cell.setCellValue("Hello from Modern .NET 9 using Apache POI!");

    Console.WriteLine("Writing file to disk...");
    using var fileOut = new java.io.FileOutputStream("output.xlsx");
    workbook.write(fileOut);
    
    Console.WriteLine("Done!");
}
catch (Exception ex)
{
    Console.WriteLine("Error: " + ex.Message);
}
