Getting Started with SQLite Editor Online - A Complete Guide

SQLite Editor Online makes it incredibly easy to work with SQLite databases directly in your browser. No downloads, no installations - just upload your database and start editing. This comprehensive guide will walk you through every feature and help you get the most out of our free tool.

What is SQLite Editor Online?

SQLite Editor Online is a free, web-based tool that allows you to:

Best of all, everything happens in your browser - your data never leaves your computer, ensuring complete privacy and security.

Step 1: Upload Your Database

Getting started is as simple as dragging and dropping your SQLite file into the editor.

Supported File Formats

File Size Limits

Currently, you can upload database files up to 50MB in size. This limit ensures optimal performance in your browser.

💡 Pro Tip: Creating a Sample Database

Don't have a SQLite database to test with? You can create one quickly using the SQL CLI once you're in the editor, or download sample databases from SQLite's official website.

Step 2: Exploring the Interface

Once your database is uploaded, you'll see the main interface with several key areas:

1. Sidebar - Table Navigation

The left sidebar shows all tables in your database. Click on any table name to view its contents in the main area.

2. Main Viewer - Data Display

The central area displays your table data in a clean, spreadsheet-like format. Here you can:

3. SQL CLI - Query Execution

The SQL command line interface allows you to execute custom queries against your database.

Step 3: Editing Your Data

One of the most powerful features is the ability to edit data directly in the browser.

In-Place Editing

Simply click on any cell to start editing. Your changes are automatically saved when you:

Adding New Rows

Use the SQL CLI to insert new records:

-- Add a new user
INSERT INTO users (name, email, created_at) 
VALUES ('John Doe', 'john@example.com', datetime('now'));

-- Add multiple records at once
INSERT INTO products (name, price, category) VALUES 
    ('Laptop', 999.99, 'Electronics'),
    ('Book', 19.99, 'Education'),
    ('Coffee Mug', 12.50, 'Kitchen');

Updating Existing Data

Besides in-place editing, you can use SQL for bulk updates:

-- Update all prices in a category
UPDATE products 
SET price = price * 0.9 
WHERE category = 'Electronics';

-- Update specific records
UPDATE users 
SET status = 'active' 
WHERE email LIKE '%@company.com';

Step 4: Using the SQL CLI

The SQL CLI is where the real power lies. You can execute any valid SQLite command.

Common Commands

-- View table structure
.schema users

-- List all tables
.tables

-- Show database info
.dbinfo

-- Execute SELECT queries
SELECT * FROM users WHERE created_at > '2023-01-01';

-- Create new tables
CREATE TABLE categories (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL UNIQUE,
    description TEXT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Advanced Queries

The SQL CLI supports complex operations like joins and subqueries:

-- Complex JOIN query
SELECT 
    u.name as user_name,
    COUNT(o.id) as order_count,
    SUM(o.total) as total_spent
FROM users u
LEFT JOIN orders o ON u.id = o.user_id
GROUP BY u.id, u.name
HAVING total_spent > 100
ORDER BY total_spent DESC;

-- Subquery example
SELECT name, email FROM users 
WHERE id IN (
    SELECT DISTINCT user_id 
    FROM orders 
    WHERE created_at > date('now', '-30 days')
);

Step 5: Filtering and Sorting Data

SQLite Editor Online provides intuitive ways to explore your data:

Column Sorting

Click on any column header to sort the data. Click again to reverse the sort order.

Data Filtering

Use the filter functionality to find specific records quickly. You can filter by:

Step 6: Managing Database Schema

You can modify your database structure using SQL commands:

Adding New Tables

CREATE TABLE blog_posts (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    title TEXT NOT NULL,
    content TEXT,
    author_id INTEGER,
    published_at TIMESTAMP,
    status TEXT DEFAULT 'draft',
    FOREIGN KEY (author_id) REFERENCES users(id)
);

Modifying Existing Tables

-- Add new column
ALTER TABLE users ADD COLUMN phone TEXT;

-- Create index for better performance  
CREATE INDEX idx_users_email ON users(email);

-- Drop table if needed
DROP TABLE IF EXISTS old_table;

Step 7: Exporting Your Database

Once you've made your changes, you can download the modified database file.

Export Process

  1. Click the "Export" button in the top-right corner
  2. The modified database will be downloaded with an _edited suffix
  3. Your original file remains unchanged

✅ Best Practice: Regular Exports

Export your database regularly while working to avoid losing changes. The browser storage is temporary and will be cleared when you close the tab.

Privacy and Security

Your data security is our top priority:

Tips and Tricks

1. Use Keyboard Shortcuts

2. Work with Large Datasets

For better performance with large tables:

-- Use LIMIT to paginate results
SELECT * FROM large_table LIMIT 100 OFFSET 0;

-- Create indexes on frequently queried columns
CREATE INDEX idx_search_column ON large_table(search_column);

-- Use specific column selections instead of SELECT *
SELECT id, name, email FROM users WHERE active = 1;

3. Backup Your Work

Since the editor works with temporary browser storage:
