Extract text from SQLite 3 databases (DB3)
To convert DB3 databases to another format, you need DB Browser for SQLite or other Database software.
To convert other file formats to the "Relational Database File" file type, you need software like DB Browser for SQLite or a similar tool.
The .DB3 file format is a complete relational database stored in a single cross-platform file. It is the standard format used by SQLite version 3 to store tables, indices, triggers, and views. Developers embed these files directly into mobile apps, web browsers, and desktop software for local data storage.
To open or query a .DB3 file, you need specialized database management software like DB Browser for SQLite or DBeaver.
Users face several challenges with .DB3 files. They are binary files, meaning you cannot open them in a standard text editor. Standard web browsers and office applications do not support them natively. Attempting to open a .DB3 file in Microsoft Notepad results in unreadable characters. To read the data, you must write SQL queries. Standard online converters fail to process this format because extracting the data requires a database engine to execute these queries and export the results table by table.
The most practical conversion targets are CSV for spreadsheet use, SQL for database migration, or JSON for web applications. Converting to flat formats like CSV means you will lose structural relationships, indices, and triggers.
This file format is difficult to open or convert online because it requires a server-side SQLite engine to parse the binary structure. Just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can inspect the file, detect the SQLite header, and extract readable text strings or structural metadata.
Convert.Guru analyzes your DB3 file, detects the exact format, and lets you read the text inside.
Users also converted DB3-WAL, DB3-SHM, DB3-JOURNAL, DB, SQLITE, ZIP, DATABASE, SQLITE3, DB4, POI, CSV, SQL and XML files.
If you want to convert DB3 file to CSV, BAG, PGN, MP4, SQL, DB, SQLITE, SQLITE3, MDB, ACCDB, DBF or ODB, you can use DB Browser for SQLite or similar software from the "Relational Database Storage" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, SQLITE or FRM files to DB3, try DB Browser for SQLite or another comparable tool in the "Relational Database Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DB3 converter.
