.SQLITE3 file extension

To open .SQLITE3 files on Windows, install the SQLite command-line shell (sqlite3) from SQLite’s official downloads, then open Command Prompt/PowerShell.

To open a .sqlite3 file, use the SQLite command-line tool (sqlite3) and point it at the file, or use a SQLite database viewer that supports SQLite 3. A .sqlite3 file is not a spreadsheet or text document; it’s a database file containing tables and other database objects.

How to open .SQLITE3 files

Use these platform-specific instructions to open .SQLITE3 files safely.

Windows

  1. Install the SQLite command-line shell (sqlite3) from SQLite’s official downloads, then open Command Prompt/PowerShell.
  2. Run: sqlite3 "C:\path\to\yourfile.sqlite3"
  3. At the sqlite> prompt, you can inspect it (for example, list tables with: .tables).

Mac

  1. Install or use an available sqlite3 command-line shell, then open Terminal.
  2. Run: sqlite3 "/path/to/yourfile.sqlite3"
  3. Use SQLite shell commands (for example, .tables) to explore the database.

Linux

  1. Install the sqlite3 command-line shell (often available as a package named sqlite3), then open a terminal.
  2. Run: sqlite3 "/path/to/yourfile.sqlite3"
  3. Use shell commands like .schema or .tables to view structure.

iOS

  1. If you received the file on iPhone/iPad, the most reliable approach is to transfer it to a desktop and open it with the sqlite3 command-line shell or another SQLite 3 tool.

Android

  1. If the file is app data, it may be usable only by that app; otherwise transfer the .sqlite3 file to a desktop and open it with the sqlite3 command-line shell or another SQLite 3 tool.

Security notes

  • .sqlite3 files are data files, but they can be crafted to exploit vulnerabilities in database parsers; only open untrusted databases with reputable, up-to-date SQLite software.
  • A .sqlite3 file may contain sensitive information (user data, tokens, logs) because many apps store local data in SQLite; treat it like confidential data when sharing or uploading.
  • If you plan to run SQL against an unknown database, be cautious about executing imported SQL scripts; the database file itself is not a script, but tools may allow attaching/running commands that modify data.

If you did not expect this file

This extension is usually plain data, text, or structured content—not a program by itself. The practical risk is social engineering (a scam attachment or misleading filename). For trusted senders you rarely need heavy-handed antivirus wording; use these tools when you want an extra check on unexpected downloads.

Avast

Avast offers free and premium antivirus software that protects against viruses, malware, ransomware, and phishing. Scan files before opening them to ensure safety.

Norton

Norton 360 delivers comprehensive antivirus protection, VPN, and identity theft monitoring. Scan files for threats before opening to keep your device secure.

Can't open this file?

These are the most common causes and fixes when .SQLITE3 files fail to open.

Common reasons

  • File opens as text or looks unreadable
  • “Not a database” / “file is not a database” error
  • Database is locked / cannot write
  • The app that created it won’t accept the file after you edited it

Fix steps

  1. Open it with SQLite tooling (for example, the sqlite3 command-line shell) instead of a text editor.
  2. In the sqlite3 shell, use .tables and .schema to see database objects.

OS-specific troubleshooting

What is a .SQLITE3 file?

A .sqlite3 file is an on-disk SQLite 3 database in SQLite’s defined database file format. SQLite databases are typically stored as one portable file that can be moved between machines and operating systems. The registered media type is application/vnd.sqlite3 (with application/x-sqlite3 documented as a deprecated alias).

Background

SQLite is a widely used embedded database engine that stores an entire database in a single file, which is why .sqlite3 often appears as an app data file. The contents can include tables, indexes, and other database structures used by applications to store structured data locally.

The file format is defined by SQLite and is designed to be cross-platform and self-contained. In practice, many applications choose .sqlite3 (along with .db and .sqlite) as a convenient extension for SQLite 3 databases.

For interoperability on the web and in file identification, SQLite 3 database files have an official IANA media type registration: application/vnd.sqlite3. Older usage of application/x-sqlite3 exists but is considered a deprecated alias in the IANA registration.

Common MIME types: application/vnd.sqlite3, application/x-sqlite3

Known aliases: .db, .sqlite

Common .SQLITE3 issues

File opens as text or looks unreadable

A .sqlite3 file is a binary database format, so opening it in a text editor will look like gibberish and won’t show tables/records.

  1. Open it with SQLite tooling (for example, the sqlite3 command-line shell) instead of a text editor.
  2. In the sqlite3 shell, use .tables and .schema to see database objects.

“Not a database” / “file is not a database” error

This usually means the file is not actually a SQLite 3 database, is truncated/corrupted, or is a different format using the .sqlite3 extension.

  1. Confirm the file source and that it is intended to be a SQLite 3 database (some apps use .sqlite3 for other data artifacts).
  2. Try opening a copy of the file (do not modify the original) and re-transfer/re-download the file if you suspect truncation.

Database is locked / cannot write

SQLite uses file-level locking; if another process has the database open (or the file is read-only), write operations may fail.

  1. Close any other program that might be using the same database file, then try again.
  2. Check file permissions and ensure you have write access if you need to modify the database.

The app that created it won’t accept the file after you edited it

Some applications expect a specific schema or rely on additional files/state; manual changes can break assumptions even if the database is valid.

  1. Work on a copy and keep the original unchanged for the app.
  2. If you must modify data, keep schema/table names intact and verify changes with the sqlite3 shell before returning the file to the app.

FAQ

Is .sqlite3 the same as .db or .sqlite?

Often yes: they are commonly used extensions for SQLite 3 database files. The IANA registration for SQLite 3 lists .db, .sqlite, and .sqlite3 as file extensions for application/vnd.sqlite3.

What is the correct MIME type for a .sqlite3 file?

The official IANA media type is application/vnd.sqlite3. The IANA registration notes application/x-sqlite3 as a deprecated alias.

Can I convert a .sqlite3 database to CSV or SQL text?

Yes. Using the sqlite3 command-line shell you can query tables and export results; you can also dump the database to SQL text using SQLite tooling.

Why is SQLite described as a “single-file database”?

SQLite stores an entire database in one disk file, which is designed to be portable across platforms and easy for applications to bundle or move.
