TL;DR: Syncfusion Document SDK AI Agent Tools is a .NET library that gives AI agents direct access to enterprise-grade document processing capabilities across PDF, Word, Excel, PowerPoint, Markdown, and more. Instead of building custom orchestration pipelines for document workflows, developers can register AI-callable tools and let agents dynamically create, edit, merge, convert, secure, and extract data from documents using natural language prompts.
AI agents can now reason, plan tasks, and respond intelligently to natural language prompts. But when those workflows involve documents, developers still face a major challenge.
Generating PDFs, merging Word files, extracting tables from scanned documents, converting Office formats, or applying document security typically requires complex orchestration code and multiple format-specific libraries.
Syncfusion® Document SDK AI Agent Tools solve this problem by giving AI agents direct access to enterprise-grade document processing capabilities through AI-callable tools.
With a simple registration model, AI agents can autonomously:
- Create documents
- Merge files
- Convert formats
- Extract structured data
- Apply security
- Process PDFs, Word, Excel, and PowerPoint files
- Execute multi-step document workflows dynamically
Instead of hardcoding workflows, developers can let AI agents decide which tools to invoke, how to chain operations together, and how to complete document tasks from natural language instructions.
Why traditional document automation becomes complex
Consider a request like: “Generate a quarterly report, merge it with last quarter’s summary, convert the result to PDF.”
An AI model can understand this instantly.
But executing it traditionally requires:
- Multiple document libraries
- Manual orchestration logic
- Intermediate file handling
- Conversion pipelines
- Error handling
- Format compatibility management
Developers must manually implement every step. This creates a major gap between AI reasoning and real document execution.
Introducing Syncfusion Document SDK AI Agent Tools
Syncfusion Document SDK AI Agent Tools is a .NET library that transforms traditional document APIs into AI-callable tools for autonomous workflows.
Built on top of Syncfusion’s enterprise-grade document processing engines, the library enables AI agents to dynamically create, modify, convert, secure, and extract information from:
- PDF documents
- Word files
- Excel workbooks
- PowerPoint presentations
- Markdown files
- HTML documents
- RTF content
The tools integrate with the Microsoft Agent Framework and work with providers such as:
- Azure OpenAI
- OpenAI
- Any provider compatible with Microsoft.Extensions.AI
How it works
The workflow is simple:
- A user submits a natural language request
- The AI model interprets the intent
- The agent runtime selects the required Syncfusion tools
- The tools execute document operations
- The final output is returned automatically
For example: “Merge all invoices, add a watermark, and export the final document as a PDF.”
The agent dynamically determines:
- Which tools to invoke
- Execution order
- Required parameters
- Intermediate processing steps
This enables truly autonomous document workflows.

Two flexible execution modes
Syncfusion Document SDK AI Agent Tools support two execution models designed for different application architectures and scalability requirements.
In-Memory mode
In-Memory mode keeps documents as live objects during execution, allowing tools to operate directly on document instances without repeatedly saving and loading files from storage. This approach minimizes disk I/O, improves execution speed, and enables efficient multi-step workflows. It is ideal for desktop applications, interactive assistants, rapid prototyping, and single-instance deployments.
Document storage mode
Document storage mode uses a pluggable storage backend through the IDocumentStorage interface. Documents are loaded and persisted during each operation, making the architecture stateless and horizontally scalable. This mode is ideal for cloud-native applications, distributed AI systems, scalable APIs, and enterprise automation platforms. Supported backends include Azure Blob Storage, Amazon S3, local file systems, and custom storage providers.
Build your first AI document agent
Step 1: Install the required NuGet packages using the command below:
dotnet add package Syncfusion.DocumentSDK.AI.AgentTools
dotnet add package Microsoft.Agents.AI.OpenAIStep 2: Register Syncfusion agent tools:
// Create document managers (In-Memory mode)
var wordManager = new WordDocumentManager();
var excelManager = new ExcelWorkbookManager();
var pdfManager = new PdfDocumentManager();
var presentationManager = new PresentationManager();
// Create document manager collection for cross-format tools
var repoCollection = new DocumentManagerCollection();
repoCollection.AddManager(DocumentType.Word, wordManager);
repoCollection.AddManager(DocumentType.Excel, excelManager);
repoCollection.AddManager(DocumentType.PDF, pdfManager);
repoCollection.AddManager(DocumentType.PowerPoint, presentationManager);
// Set up input/output directories
string outputDir = @"D:\Output";
string inputDir = @"D:\Input";
Directory.CreateDirectory(outputDir);
// Collect all available tools
var allTools = new List<AITool>();
// Word tools
allTools.AddRange(new WordDocumentAgentTools(wordManager, outputDir).GetTools());
allTools.AddRange(new WordOperationsAgentTools(wordManager).GetTools());
allTools.AddRange(new WordSecurityAgentTools(wordManager).GetTools());
// etc. (WordBookmarkAgentTools, WordMailMergeAgentTools, WordFindAndReplaceAgentTools, ...)
// Excel tools
allTools.AddRange(new ExcelWorkbookAgentTools(excelManager, outputDir).GetTools());
allTools.AddRange(new ExcelWorksheetAgentTools(excelManager).GetTools());

""",
tools: aiTools);Now the agent can execute document workflows from natural language prompts. For the complete getting started guide, refer to the official documentation.
Extend with custom AI Tools
If your workflows require operations beyond the built-in capabilities, you can create custom AI tools and register them alongside Syncfusion’s built-in tools.
Once registered, the agent can discover and invoke them using the same execution model, allowing teams to extend the framework while maintaining a unified agent architecture.
For the full customization guide, including both operating modes and additional examples, refer to the customization documentation.
