## 📦 Installation

```bash
pip install docx-json-replacer
```

## 🚀 Quick Start

### Command Line

```bash
# Basic usage
docx-json-replacer template.docx data.json -o output.docx

# Without -o flag, creates template_replaced.docx
docx-json-replacer template.docx data.json
```

### Python API

```python
from docx_json_replacer import DocxReplacer

# Create replacer instance
replacer = DocxReplacer('template.docx')

# Replace with JSON data
json_data = {
    "name": "John Doe",
    "company": "Acme Corp",
    "table_data": [
        {
            "cells": ["Header 1", "Header 2", "Header 3"],
            "style": {"bg": "4472C4", "color": "FFFFFF", "bold": True}
        },
        {
            "cells": ["Row 1 Col 1", "Row 1 Col 2", "Row 1 Col 3"]
        }
    ]
}

replacer.replace_from_json(json_data)
replacer.save('output.docx')
```

## 📄 Template Format

Use double curly braces for placeholders:

```
Dear {{name}},

Welcome to {{company}}!

{{table_data}}
```

Placeholders work in:
- Regular paragraphs
- Table cells
- Headers and footers
- Nested structures with dots (e.g., `{{client.name}}`)

## 📊 Table Support

### Basic Table (List of Lists)
```json
{
  "simple_table": [
    ["Header 1", "Header 2"],
    ["Row 1 Col 1", "Row 1 Col 2"]
  ]
}
```

### Styled Table with Row-Level Styling
```json
{
  "styled_table": [
    {
      "cells": ["Header 1", "Header 2", "Header 3"],
      "style": {

        "color": "FFFFFF",
        "bold": true
      }
    },
    {
      "cells": ["Data 1", "Data 2", "Data 3"],
      "style": {
        "bg": "F2F2F2"
      }
    }
  ]
}
```
