Overview

QueryBot is built with FastAPI for the backend and a responsive HTML/Bootstrap frontend. It provides a seamless experience for data analysis by allowing users to query multiple data sources through a unified SQL interface.

Features

• Multi-format Support: Query CSV, Parquet, SQLite, Excel files, and MySQL databases with a single interface.
  • Example: Users can upload a CSV file and query it directly.
• Interactive SQL Editor: Writes and executes SQL queries with syntax highlighting. The application automatically generates DuckDB queries and runs on datasets. It supports multiple files if the paths are provided separated by commas.
• Real-time Results: View query results instantly in a paginated table format
• Export Functionality: Download query results in CSV format for further analysis. Note: Currently, only CSV format is supported for export.
• Responsive Design: Works seamlessly across desktop and mobile devices
