How to Open & View SQLite (.db) Files Online Without Software
Traditionally, inspecting a SQLite database file (.db, .sqlite, or .sqlite3) required downloading and installing heavy native desktop software like DB Browser for SQLite, DBeaver, or command-line tools. The MSK Database Viewer eliminates this barrier completely. Built with cutting-edgeWebAssembly (WASM), it runs the official SQLite 3 engine directly within your modern web browser.
Quick 3-Step Guide to Inspecting Any Database File
Drag & Drop Your File
Drag your .db, .sqlite, or .sql file directly into the viewer box, or click “Open .DB / .SQL File”.
Browse Tables & Schema
Instantly view all tables and views in the left sidebar with live row counts. Switch between interactive data spreadsheet records and column DDL definitions.

Frequently Asked Questions
Common questions regarding opening, inspecting, and editing SQLite database files in the browser.
Can I view databases created with Python sqlite3?
Yes! Python creates standard SQLite3 binary files. Simply drag your database.db or app.sqlite3 file right into this tool to inspect tables and rows instantly.
Can I edit data and run custom SQL queries?
Yes. While the Database Viewer is optimized for fast read-only inspection, clicking the “Edit in SQL Studio” button seamlessly transfers your loaded database into our full-featured in-browser SQL Workbench with Monaco Editor.
How do I export tables to Excel or CSV?
Select the table you wish to export, then click the “CSV” button in the top right corner. The file downloads directly to your device and opens smoothly in Microsoft Excel or Google Sheets.
Is there any file size limit?
Because WebAssembly runs directly inside your computer's RAM, it comfortably handles database files up to several hundred megabytes depending on your device memory.
Ready to write complex queries, joins, and aggregations?
