How does CSV AI work?
The tool detects column types and names in your CSV, prompts AI to generate SQL from your natural language question, then executes the SQL in your browser directly against the CSV without data leaving your device.
Is my data private?
Yes. Your CSV data stays on your device. Only the column schema is sent to the AI model to generate SQL — the actual row data never leaves your browser.
What kind of questions can I ask?
You can ask any analytical question about your data, such as filtering, aggregating, grouping, finding top/bottom values, counting, or computing averages.
Do I need to know SQL?
No. The AI translates your natural language questions into SQL automatically. Just describe what you want to know in plain English.
