OfficeFlow

OfficeFlow is a completely free and open source library for reading, creating and editing Word, Excel and PowerPoint documents.

Motivation

There are three reasons why this library is being developed:

• Most open source solutions offer an inconvenient and ugly API
• Also, these open source solutions are limited in functionality
• Paid libraries have closed source code

My dream is to give the .NET world a free alternative that will fully cover the needs of all developers to interact with the Office software suite. This means that I'm not going to make money by selling access to this library.

Implementation Status

The library is not ready yet. However, opening and saving documents with .docx extension is already implemented. You can also create and read sections and paragraphs from a document:

var document = new WordDocument(WordDocumentType.Docx);

var section = document.AppendSection();
var paragraph = section.AppendParagraph();
paragraph.AppendText("Hello, OfficeFlow!");

document.SaveTo("OfficeFlow.docx");

document.Close();
