About SQL Formatter

Format and beautify SQL queries with consistent indentation, keyword casing, and proper line breaks. Supports SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER, and DROP statements. All processing happens in your browser — no data is ever uploaded.

Smart Formatting

Automatically indents SQL with keywords on new lines. Configurable indent width (2 or 4 spaces). Handles nested subqueries, JOINs, and complex WHERE clauses.

Keyword Casing

Choose between UPPERCASE and lowercase for SQL keywords. Consistent casing makes queries easier to read and maintain across your team.

Minification

Compress SQL queries into a single line for compact storage. Great for embedding queries in application code or saving space in configuration files.

100% Private

All processing happens in your browser. Your SQL queries, database schemas, and sensitive data never leave your device. No server-side processing.

📋 Common Use Cases

Reviewing Complex Queries

Format a long, nested SQL query before a code review so your teammates can understand the logic at a glance.

Debugging Database Issues

Beautify a raw query from application logs to spot missing joins, misplaced conditions, or syntax problems more easily.

Standardizing Team SQL Style

Run all team queries through the formatter to enforce consistent keyword casing and indentation across your codebase.

Preparing Documentation Examples

Format SQL snippets for technical documentation or blog posts so readers can follow the query structure clearly.
