A smart Markdown to Word document generator with automatic chart generation (pie charts, bar charts, line charts) and flexible template mechanism, enabling rapid generation of formatted Word documents with rich visualizations for various scenarios.

Repository: https://github.com/luyike221/dify_markdown_to_word_plugin.git

Overview

Smart Doc Generator is a powerful Dify plugin that converts Markdown content into professionally formatted Word documents (.docx). The plugin's standout feature is its intelligent chart generation system that automatically recognizes data patterns in Markdown and generates beautiful, professional charts (pie charts, bar charts, line charts) directly embedded in Word documents. Combined with a flexible template system, it enables rapid generation of data-rich, visually appealing documents.

🚀 Quick Start - Usage Workflow

Core Usage Philosophy

The plugin follows a simple three-step workflow:

Markdown Content → Template Selection → Word Document
         ↓                ↓                    ↓
    Your content    Choose style      Professional output

Step-by-Step Usage Guide

Step 1: Prepare Your Markdown Content

Start with your Markdown text - this can be:

• Plain Markdown text from your workflow
• Generated content from AI models
• Structured data formatted as Markdown tables
• Any Markdown-formatted content

Example:

# Sales Report Q4 2024

## Monthly Sales Data

| Month | Sales | Growth |
|-------|-------|--------|
| Oct   | 1000  | +10%   |
| Nov   | 1500  | +50%   |
| Dec   | 1800  | +20%   |

Step 2: Choose Your Template/Theme

Select a pre-built theme that matches your use case:

Use Case	Recommended Theme	Why
Business reports	business	Professional, modern styling
Academic papers	academic	Times New Roman, double spacing
System alerts	default	Formal, red accent colors
Technical docs	minimal	Clean, minimalist design
Presentations	dark	Dark theme suitable for screens
Colorful reports	colorful	Rich color scheme

Quick Selection:

templates: "business"  # Just specify the theme name

Step 3: (Optional) Add Charts

If your document needs visualizations, enable chart generation:

enable_charts: true
chart_data: |
  {
    "charts": [
      {
        "type": "bar",
        "title": "Monthly Sales Trend",
        "position": "after:Monthly Sales Data",
        "data": {
          "Oct": 1000,
          "Nov": 1500,
          "Dec": 1800
        }
      }
    ]
  }

Step 4: Get Your Word Document

The plugin returns:

• Word document (.docx) - Ready to download and use
• JSON metadata - Conversion summary and settings

Usage Patterns

Pattern 1: Simple Document Generation

For basic Markdown-to-Word conversion:

• Provide markdown_text
• Select templates (or use default)
• Get Word document

Pattern 2: Document with Charts

For data-rich documents:

• Provide markdown_text with data tables
• Set enable_charts: true
• Provide chart_data with chart specifications
• Get Word document with embedded charts

Pattern 3: Custom Styled Document

For specific styling requirements:

• Provide markdown_text
• Use style_config for advanced customization
• Or override individual settings (font_family, font_size, etc.)
• Get custom-styled Word document

Chart Generation Guide

How Chart Generation Works

The chart generation feature allows you to automatically insert professional charts into your Word documents. Here's how it works:

1. Enable Chart Generation: Set enable_charts: true in your tool parameters
2. Provide Chart Data: Pass chart data in JSON format via the chart_data parameter
3. Specify Chart Position: Define where charts should appear in the document using the position field
4. Automatic Rendering: The plugin generates the chart image and inserts it into the Word document

Chart Data Format

The chart_data parameter accepts a JSON object with the following structure:

{
  "charts": [
    {
      "type": "pie" | "bar" | "line",
      "title": "Chart Title",
      "position": "after:Heading Text" | "before:Heading Text" | "after:Table Title",
      "data": {
        "Label1": value1,
        "Label2": value2,
        ...
      }
    }
  ]
}

Chart Types

Pie Charts

Perfect for showing proportions and percentages:

{
  "type": "pie",
  "title": "Market Share",
  "position": "after:Market Analysis",
  "data": {
    "Product A": 35,
    "Product B": 25,
    "Product C": 40
  }
}

Bar Charts

Ideal for comparing values across categories:

{
  "type": "bar",
  "title": "Monthly Sales",
  "position": "after:Sales Data",
  "data": {
    "Jan": 1000,
    "Feb": 1500,
    "Mar": 1200
  }
}

Line Charts

Great for showing trends over time:

{
  "type": "line",
  "title": "Revenue Trend",
  "position": "after:Financial Overview",
  "data": {
    "Q1": 50000,
    "Q2": 55000,
    "Q3": 60000,
    "Q4": 65000
  }
}

Chart Positioning

Charts can be positioned relative to document elements:

• "after:Heading Text" - Inserts chart after the first occurrence of the specified heading
• "before:Heading Text" - Inserts chart before the specified heading
• "after:Table Title" - Inserts chart after a table with the specified title

Custom Templates

Creating a New Theme

1. Edit Theme Configuration: Add a new theme in src/templates/themes/theme_config.yaml:

themes:
  my_custom_theme:
    name: "My Custom Theme"
    description: "Theme suitable for my business scenario"
    style_template: "default.yaml"  # Can reuse existing style template
    color_scheme:
      primary: "#0066cc"
      secondary: "#666666"
      # ...
    overrides:
      fonts:
        body:
          name: "Microsoft YaHei"
          size: 12
      # Other override settings...

2. Create New Style Template (optional): If you need a completely new style configuration, create a new YAML file in the src/templates/styles/ directory

3. Use New Theme: Specify the theme name when calling the tool:

templates: "my_custom_theme"

Troubleshooting

• If Dify results show an empty files array, ensure your environment uses a plugin version that supports file BLOB returns (this project already supports it)
• Very large Markdown inputs may require longer conversion times
• When customizing themes, ensure YAML format is correct to avoid syntax errors
• Font names must be installed on the system, otherwise default fonts will be used
• Color values in style templates use hexadecimal format (e.g., #d32f2f)

Template System Advantages

1. Flexibility: Through theme and style template separation, achieve highly flexible style customization
2. Maintainability: Centralized style configuration management, easy to maintain and update
3. Extensibility: Easily add new themes and style templates without modifying core code
4. Consistency: Ensure document style consistency through templates
5. Usability: Predefined themes ready to use, lowering the barrier to entry
