SQL Formatter - Beautify & Format SQL Queries Online

Free Online SQL Formatter

The Tooloogle SQL Formatter rewrites cramped, single-line, or inconsistent SQL into clean, properly indented queries you can read at a glance. Supports every major SQL dialect — MySQL, PostgreSQL, SQL Server (T-SQL), Oracle (PL/SQL), and SQLite — with dialect-specific keyword handling.

What It Formats

• SELECT, INSERT, UPDATE, DELETE, and MERGE statements

• Complex joins (INNER, LEFT, RIGHT, FULL, CROSS)

• Subqueries and Common Table Expressions (CTEs)

• Window functions (ROW_NUMBER(), OVER (PARTITION BY ...))

• DDL statements (CREATE TABLE, ALTER, DROP, INDEX)

• Stored procedures and triggers

Customisation Options

• Dialect — pick MySQL, PostgreSQL, T-SQL, PL/SQL, SQLite, Snowflake, BigQuery, or generic ANSI SQL.

• Keyword case — UPPERCASE, lowercase, or preserve.

• Indent size — 2, 4, or 8 spaces, or tabs.

• Comma placement — trailing or leading commas in SELECT lists.

• Line wrap — max line length before wrapping long expressions.

How to Use

1. Paste your SQL into the input box.

2. Pick the dialect and formatting preferences.

3. Click Format — the cleaned-up query appears instantly.

4. Copy or download the result.

Why Format SQL?

A formatted query reveals join structure, makes it easy to spot missing WHERE clauses, and helps reviewers catch subtle bugs (a comma after the last column, a misplaced AND). Standardised SQL also produces clean diffs in version control and makes performance tuning sessions much faster.

Privacy

Formatting runs entirely in your browser. Your SQL — which often contains schema names, business logic, or sensitive filters — is never uploaded or logged.
