Free SQLite Viewer — Open and Browse SQLite Databases Online

About the Free SQLite Viewer

The FinancialDataTools.com SQLite Viewer is a free, browser-based tool for opening, inspecting, and exporting SQLite database files. It runs entirely in your browser using WebAssembly — no file is ever uploaded to any server.

Supported File Formats

Open any SQLite database file: .db, .sqlite, .sqlite3, .db3, and other SQLite-compatible formats. Ideal for financial databases, brokerage exports, trading platforms, and accounting software.

Key Features

Browse tables and rows in a spreadsheet-style grid. Sort any column ascending or descending. Filter rows by column values or custom conditions. Run any SELECT SQL query using the built-in SQL panel. Inspect table schema, column types, constraints, and indexes. Export data to CSV, JSON, TSV, or Excel (.xlsx) — including multi-table workbook export.

Privacy and Security

All database processing happens inside your browser using the sql.js WebAssembly engine. No file content is transmitted to any server. Your financial data stays private on your device. Closing the browser tab clears all data from memory immediately.

Use Cases for Financial Data
