# Excel to RVT Import

> **Note:** RVT is the file format. Examples may reference Autodesk® Revit® APIs. Autodesk and Revit are registered trademarks of Autodesk, Inc.

## Business Case

### Problem Statement
External data (costs, specifications, classifications) lives in Excel but needs to update Revit:
- Cost estimates need to link to model elements
- Classification codes need assignment
- Custom parameters need population
- Manual entry is slow and error-prone

### Solution
Automated import of Excel data into Revit using the DDC ImportExcelToRevit tool and Dynamo workflows.

### Business Value
- **Automation** - Batch update thousands of parameters
- **Accuracy** - Eliminate manual data entry errors
- **Sync** - Keep external data in sync with model
- **Flexibility** - Update any writable parameter

## Technical Implementation

### Methods
1. **ImportExcelToRevit CLI** - Direct command-line update
2. **Dynamo Script** - Visual programming approach
3. **Revit API** - Full programmatic control

### ImportExcelToRevit CLI

```bash
ImportExcelToRevit.exe <model.rvt> <data.xlsx> [options]
```

| Option | Description |
|--------|-------------|
| `-sheet` | Excel sheet name |
| `-idcol` | Element ID column |
| `-mapping` | Parameter mapping file |
