SQLite Database Viewer – Open and Query SQLite Files Free Online

Use the free SQLite Database Viewer below: your data never leaves your browser — all work happens on your device, and nothing is uploaded to any server.

A SQLite database is a single file that holds whole tables of data, and it shows up in surprising places: phone apps, browsers, small programs, and exported datasets all use it. The trouble is that opening one usually means installing database software first. The SQLite Database Viewer removes that step. Choose a .db or .sqlite file from your own computer, and the tool opens it right in your browser so you can look at the tables and run queries on them.

Everything happens on your own device. The file is read by your browser and never sent to any server, which matters when the database holds personal or work data. The tool uses sql.js, a version of SQLite compiled to run in the browser, loaded from a public content delivery network. If that library cannot load, the tool says so plainly instead of pretending to work, and reloading the page usually fixes it.

To use it, press Choose File and pick your database file, or press Load demo database to try it with a small built-in example of three books. Once a database is loaded, its table names appear on the page. Then type a query in the box and press Run query. A typical first query is SELECT * FROM books LIMIT 20, which shows the first twenty rows of a table. You can filter with WHERE, sort with ORDER BY, and count with COUNT, just like in any SQLite tool.

The viewer is read-only by design, and that is a safety feature, not a missing feature. Only SELECT queries are allowed to run. Anything that would change data, such as INSERT, UPDATE, DELETE, DROP, ALTER, or CREATE, is refused before it reaches the database. Your original file on your computer is never modified, so you can explore freely without worrying that a typo will delete a table.

Reading a database this way is useful in several everyday situations. A student can inspect a dataset from a course without installing software on a shared computer. A small business owner can check an export from an app to confirm the rows are really there. A curious user can open an app backup file and see what it actually stores. In each case the goal is the same: look, understand, and leave the file untouched.

One honest limit is size. Very large database files can be slow in a browser, because the whole file is loaded into memory. For small and medium files, the kind most people actually meet, it works smoothly. Results are also capped at the first 500 rows on screen, so a query that matches a million rows stays readable instead of freezing the page.

If a query fails, read the error message first. The most common problems are a misspelled table name, a missing quote around text in a WHERE clause, or a query that is not a SELECT. The table list on the page shows the exact table names, which removes the guessing. Text values need single quotes, like WHERE author = ‘Ana Ruiz’, while numbers do not.

How to view a SQLite database

  1. Choose a .db or .sqlite file from your computer, or load the demo database.
  2. Check the table names shown on the page.
  3. Type a SELECT query and press Run query.
  4. Read the results table, up to 500 rows at a time.

Frequently asked questions

Is my database uploaded? No. It is read in your browser only, and the original file is never changed.

Can I edit data with it? No. Only SELECT queries run, so the viewer is for looking, not changing.

What if the engine fails to load? That means the sql.js library did not reach your browser. Check your connection and reload the page.

Which files does it open? Files ending in .db, .sqlite, or .sqlite3 that are genuine SQLite databases.

SQLite files are everywhere, but the software to open them is not always at hand. This viewer puts a safe, read-only window on any database file, with no install, no account, and no upload — just the data, in your browser, exactly as it is.
