How to Integrate Spire.Office into Your .NET Workflow

This guide shows a concise, practical path to add Spire.Office to a .NET project, use its core libraries (Word, Excel, PDF), and automate common document tasks. Examples use C# and .NET 6+; adapt to older frameworks by selecting compatible DLLs or NuGet versions.

1. Choose edition and install

Decide: Free (with page/row limits) or commercial Spire.Office.

Install via NuGet (recommended) or download DLLs from the vendor.

NuGet (Package Manager):

Code
Install-Package Spire.Office

.NET CLI:

Code
dotnet add package Spire.Office

2. Project setup

Target .NET 6/7/8+ (or a supported framework listed by the package).
Add using directives per component you need:
- Word: using Spire.Doc;
- Excel: using Spire.Xls; (or Spire.Spreadsheet)
- PDF: using Spire.Pdf;
If you downloaded DLLs, add references to the appropriate Bin folder matching your target framework.

3. Licensing

For production, obtain a license key from E-iceblue and apply per their docs (usually via license file or API call). Free edition works for development/testing but has limits.

4. Typical tasks and sample code

Note: these are minimal, ready-to-run snippets. Add error handling and dispose patterns for production.

Create a Word document and save as PDF “`csharp using Spire.Doc; using Spire.Doc.Documents;

var doc = new Document(); Section section = doc.AddSection(); Paragraph p = section.AddParagraph(); p.AppendText(“Hello from
