Getting started#

Play with a live demo#

The best way to experience Datasette for the first time is with a demo:

Follow a tutorial#

Datasette has several tutorials to help you get started with the tool. Try one of the following:

Datasette in your browser with Datasette Lite#

Datasette Lite is Datasette packaged using WebAssembly so that it runs entirely in your browser, no Python web application server required.

You can pass a URL to a CSV, SQLite or raw SQL file directly to Datasette Lite to explore that data in your browser.

This example link opens Datasette Lite and loads the SQL Murder Mystery example database from Northwestern University Knight Lab.

Try Datasette without installing anything using Glitch#

Glitch is a free online tool for building web apps directly from your web browser. You can use Glitch to try out Datasette without needing to install any software on your own computer.

Here's a demo project on Glitch which you can use as the basis for your own experiments:

Glitch allows you to "remix" any project to create your own copy and start editing it in your browser. You can remix the datasette-csvs project by clicking this button:

Find a CSV file and drag it onto the Glitch file explorer panel - datasette-csvs will automatically convert it to a SQLite database (using sqlite-utils) and allow you to start exploring it using Datasette.

If your CSV file has a latitude and longitude column you can visualize it on a map by uncommenting the datasette-cluster-map line in the requirements.txt file using the Glitch file editor.

Need some data? Try this Public Art Data for the city of Seattle - hit "Export" and select "CSV" to download it as a CSV file.

For more on how this works, see Running Datasette on Glitch.

Using Datasette on your own computer#

First, follow the Installation instructions. Now you can run Datasette against a SQLite file on your computer using the following command:

datasette path/to/database.db

This will start a web server on port 8001 - visit http://localhost:8001/ to access the web interface.

Add -o to open your browser automatically once Datasette has started:

datasette path/to/database.db -o

Use Chrome on OS X? You can run datasette against your browser history like so:

datasette ~/Library/Application\ Support/Google/Chrome/Default/History --nolock

The --nolock option ignores any file locks. This is safe as Datasette will open the file in read-only mode.

Now visiting http://localhost:8001/History/downloads will show you a web interface to browse your downloads data:

Downloads table rendered by datasette

http://localhost:8001/History/downloads.json will return that data as JSON:

    "database": "History",
    "columns": [
    "rows": [

http://localhost:8001/History/downloads.json?_shape=objects will return that data as JSON in a more convenient format:

    "rows": [
            "start_time": 13097290269022132,
            "interrupt_reason": 0,
            "hash": "",
            "id": 1,
            "site_url": "",
            "referrer": "",
