## FAQ

### Is my data uploaded to a server?

No, the conversion happens locally where your data is located, and file contents never enter the model's context.

### How does the server handle data types like leading zeros or long account numbers?

The engine infers types per column; a column only converts to numbers if every value survives the round trip exactly, preserving leading zeros and long numbers.

### What are the system requirements to run this server?

You need Node.js version 18 or higher to use the MCP server.
