Getting Started

So, you probably want to jump up and start coding your document processing application on C#, F# or Visual Basic right away? Let us show you how to do it in a few easy steps.

Run Install-Package Aspose.Words from the Package Manager Console in Visual Studio to fetch the NuGet package. If you want to upgrade to the latest package version, please run Update-Package Aspose.Words.

You can run the following code snippets in C# to see how our library works. Also feel free to check out the GitHub Repository for other common use cases.

Create a DOCX using C#

Aspose.Words for .NET allows you to create a blank Word document and add content to the file.

// Create a Word document.
Document doc = new Document();

// Use a DocumentBuilder instance to add content to the file.
DocumentBuilder builder = new DocumentBuilder(doc);

// Write a new paragraph to the document.
builder.Writeln("This is an example of a Word document created in C#");

// Save it as a DOCX file. The output format is automatically determined by the filename extension.
doc.Save(dir + "OutputWordDocument.docx");

Create a PDF in C#

Aspose.Words for .NET allows you to create a new PDF file and fill it with data.

// Create a PDF document.
Document pdf = new Document();

// Use a DocumentBuilder instance to add content to the file.
DocumentBuilder builder = new DocumentBuilder(pdf);

// Write a new paragraph to the document.
builder.Writeln("This is an example of a PDF document created using C#");

// Save it as a PDF file.
pdf.Save(dir + "OutputDocument.pdf");

Convert a Word document to HTML with C#

You can convert Microsoft Word to PDF, XPS, Markdown, HTML, JPEG, TIFF, and other file formats. The following snippet demonstrates the conversion from DOCX to HTML:

// Load a Word file from the local drive.
Document doc = new Document(dir + "InputWordDocument.docx");

// Save it to HTML format.
doc.Save(dir + "OutputHtmlDocument.html");

Import a PDF and save as a DOCX via C#

In addition, you can import a PDF file into your .NET application and export it as a DOCX format file without the need to install Microsoft Word:

// Load a PDF file from the local drive.
Document pdf = new Document(dir + "InputDocument.pdf");

// Save it to DOCX format.
pdf.Save(dir + "OutputWordDocument.docx");
