### Description (declared)

# excel-diff2-mcp

MCP (Model Context Protocol) server for comparing Excel files with hierarchical module matching.

## Features

- **Hierarchical Module Matching**: Match Excel data by multiple levels of functional modules
- **Stacked Output**: Output two tables stacked in a single result
- **Dual Output Formats**: Support both CSV and Markdown output
- **Flexible Input**: Accept HTTP(S) URLs or Base64-encoded file content
- **Auto Header Detection**: Automatically detect header rows
- **Merged Cell Handling**: Fill merged cells downward for accurate comparison

## Installation

```

## Usage

### Command Line

```bash
excel-diff2-mcp
```

### As MCP Tool

```python
from mcp.client.session import Session

async with Session() as session:
    result = await session.call(
        "compare_excel",
        file1="https://example.com/file1.xlsx",
        file2="https://example.com/file2.xlsx",
        compare_columns=["一级功能模块", "二级功能模块"],
        output_format="markdown",  # optional: "csv" (default) or "markdown"
    )
```

### compare_excel Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `file1` | str | Yes | First Excel file (URL or Base64 content) |

```

**Dual array** (different columns per table):
```python
[["一级功能模块", "二级功能模块"], ["一级功能点", "二级功能点"]]
```

## Output
