Word (DOCX) Document Processing

Overview

Create, edit, and convert Word (.docx, .doc) files using the Syncfusion Word Library. This skill supports two operational modes — generating C# code for the user's project or executing tasks directly through a CSX script.

Key Capabilities

• Create & Edit: Documents (.docx, .doc, .rtf, .txt, .xml), paragraphs, headings, styles, lists, tables, charts, shapes, images, hyperlinks, bookmarks, watermarks, headers/footers, form fields, content controls, SmartArt, OLE objects
• Advanced Features: Mail merge (DataTable, JSON, XML, custom objects), track changes, comments, mathematical equations (LaTeX), compare/split/merge documents, table of contents
• Conversion: Word to PDF (font embedding, PDF/A, accessibility), Word to Image (PNG, JPEG, BMP, TIFF), HTML ↔ DOCX, RTF ↔ DOCX, Text ↔ DOCX, XML ↔ DOCX
• Security: Password encryption/decryption, document protection with editable ranges, macro management

Prerequisites

• .NET SDK 8+ and dotnet-script: dotnet tool install -g dotnet-script
• Syncfusion License: https://www.syncfusion.com/products/communitylicense

Quick Start Examples

Example 1: Generate Code (Mode 1)

User: "Show me how to create a Word document with a table"

Result: C# code snippet displayed (no files created)

Example 2: Execute Task (Mode 2)

User: "Create a Word document with a table at output/report.docx"

Result: Physical file created at specified path

Two Modes — Choose Based on User Intent

Before choosing a mode, infer what the user wants to accomplish:

Mode 1: Generate C# Code for the User's Project (default)

Use this mode when the user wants to view, write, review, refactor, or modify C# code related to Word processing.

Trigger keywords: "show me how", "how to", "how can I", "how do I", "provide code", "provide an example", "give an example", "demonstrate", "code snippet", "sample code", "example", "sample", "give me", "show me", "Program.cs", "example code", "generate code for", "codesnippet"

Workflow:

Step 1 — Detect the Application Type and Suggest the Correct NuGet Package(s)

• Inspect the workspace project files (.csproj, web.config, App.config, Startup.cs, Program.cs, etc.) and use the detection signals table in references/nuget-packages.md to identify the application type.
• Look up the correct package(s) from references/nuget-packages.md based on the detected app type and tell the user to install them before generating any code.

Step 2 — Generate Code from Reference Files Only

Do NOT invent, guess, or suggest any API, method, property, class, or namespace not explicitly present in the reference files.

• Read the relevant references/*.md file(s) for the requested feature
• Build C# code strictly from the APIs and snippets found in those files
• Select the correct snippet variant based on the app type detected in Step 1:
  • Windows-specific apps (WinForms, WPF, .NET Framework Console, ASP.NET MVC4/5, UWP) → use Windows-specific snippets
  • Cross-platform apps (ASP.NET Core, .NET Core/.NET 5+ Console, Blazor, MAUI, Xamarin) → use cross-platform / .Net.Core snippets
• Do not create or run any .csx script

---

Mode 2: Execute via CSX Script (does not touch project files)

Use this mode only when the user explicitly requests execution, file generation, or a fully produced output (such as a completed Docx file).

Trigger keywords: "create a word document", "make a document", "generate a document", "open", "edit", "modify", "change" a .docx file, "without modifying my project", "run a csx script", or when the user provides a file path (e.g., output/report.docx).

Workflow:

Step 1 — Create Temp CSX Script

• Start with references/template.csx as the base
• Create at: {skill-root}/syncfusion-dotnet-word/scripts/temp-{uniqueId}.csx (e.g., skill-root = .codestudio/skills)
• Use random GUID for unique filename (e.g., temp-a3f7b2c1.csx); never create in workspace root

Step 2 — Build Script from Reference Files

• Do NOT invent APIs/methods not in reference files
• Read relevant references/*.md file(s) and extract code snippets
• Replace all placeholders: file paths, document properties, data values, field names, etc.

Step 3 — Execute Script

• Run: dotnet script {skill-root}/syncfusion-dotnet-word/scripts/temp-{uniqueId}.csx
• Verify successful execution and capture any errors

Step 4 — Clean Up and Report

• Delete the temp .csx file after execution
• Report SUCCESS/ERROR with output file path(s) and any error messages with fixes

Rules

• Output files go in ./output/ directory
• Temp .csx scripts must be created inside {skill-root}/syncfusion-dotnet-word/scripts/ — never in the workspace root or customer scripts/ folder
• Use license key from SyncfusionLicense.txt at workspace root or env var SYNCFUSION_LICENSE_KEY
• Never use Python libraries (e.g., python-docx)
• Never leave temp .csx files after execution
