FAQ

Frequently asked questions about ExploreMyData.

Is my data uploaded to a server?

No. All processing happens in your browser using DuckDB WASM. Your data never leaves your machine.

What's the maximum file size?

It depends on your browser's available memory. Files up to ~100 MB work well in most cases. Parquet files are the most efficient format for large datasets.

Do I need to create an account?

No. ExploreMyData is free and requires no signup. Just open the app and upload a file.

What SQL dialect does it use?

DuckDB SQL, which is PostgreSQL-compatible with additional features. See the DuckDB SQL Reference.

Can I join two files?

Yes. Upload both files (they appear as tabs), then use the Join operation to combine them.

What does the AI intent feature do?

It converts natural language descriptions (like "remove rows where revenue is negative") into SQL expressions. You need to provide an API key in Settings.

Is my API key stored safely?

Your API key is stored in your browser's local storage and sent directly to the LLM provider. It never passes through our servers.

Can I export my results?

Yes. Click the Export button to download as CSV or Parquet.
