- Data analysts who work primarily with BI tools (Power BI, Tableau)
- Non-technical users who need to understand BI file contents
- Teams that need to quickly explore and document BI assets

**Key Principles:**
- **Zero CLI Knowledge Required**: Point-and-click interfaces
- **Instant Gratification**: Quick preview and scan capabilities
- **Learning-Oriented**: Help analysts understand BI file structure
- **Windows-Native**: Familiar Windows UI patterns
- **Self-Service**: Minimal IT support required

## 🚀 Implementation Options (Priority Order)

### 1. Windows Explorer Integration (Quick Win)

**Right-Click Context Menu Extension**

Create a Windows Shell Extension that adds "Scan with BI-Doc" to the right-click menu for .pbix, .twb, and .twbx files.

```text
File Explorer Context Menu:
├── Open
├── Open with...
├── Scan with BI-Doc →
│   ├── Quick Preview (HTML)
│   ├── Generate Documentation
│   ├── Export to Excel
│   └── Settings...
```

**Implementation:**
- Windows Shell Extension (C# or PowerShell)
- Background CLI calls with progress dialogs
- HTML output that opens in default browser
- Minimal installation (MSI package)

**Benefits:**
- Zero learning curve
- Works with existing Windows workflows
- No need to open command prompt
- Immediate access from file location

### 2. PowerShell Module (Windows-Native CLI)

**Analyst-Friendly PowerShell Commands**

Wrap the CLI in PowerShell cmdlets that feel native to Windows administrators and power users.

```powershell
# Install the module
Install-Module BIDocumentation

# Scan a single file
Scan-BIFile "C:\Reports\sales.pbix" -OutputPath "C:\Docs\"

# Scan multiple files with progress
Get-ChildItem "C:\Reports\*.pbix" | Scan-BIFile -ShowProgress

# Quick preview in console
Get-BIFileInfo "sales.pbix" | Format-Table

# Export to Excel
Scan-BIFile "dashboard.twbx" | Export-Excel "analysis.xlsx"
```
