Upload a spreadsheet. Ask anything in plain English. Get results — no SQL, no setup.
Drop in a CSV or XLSX file up to 20 MB. LexSQL reads the structure, infers column types, and prepares it for instant queries.
Type your question exactly as you would ask a colleague. No SQL syntax, no schema knowledge, no configuration.
Results arrive as a formatted table with chart suggestions and the exact SQL it ran — transparent and auditable.
Each account gets its own DuckDB database. Your data never touches another user's context — stored separately, queried separately.
GPT-4o converts your natural language question to optimised DuckDB SQL in under a second, every time.
Every generated query is validated against a strict whitelist before execution. No writes, no drops, no mutations — ever.
LexSQL recommends the right chart type — bar, line, or pie — based on your result shape, with one-click PNG export.
Context carries across messages. Follow-up questions build on previous results without repeating yourself.
Upload files up to 20 MB. Data is stored in DuckDB for fast columnar queries with no upload lag on subsequent questions.
