SQL Query Formatter Pro

The formatter supports MySQL (backtick identifiers, LIMIT/OFFSET syntax), PostgreSQL (double-quoted identifiers, $1/$2 parameter placeholders), and SQLite (PRAGMA support, no stored procedures). Standard ANSI SQL keywords are handled for all dialects.

Common Table Expressions are formatted with each CTE on its own lines, properly indented. Multiple CTEs are separated clearly, and the final SELECT that references them is formatted at the base indentation level, making complex analytical queries much easier to read.

Syntax highlighting applies distinct colors to SQL keywords (SELECT, FROM, WHERE), string literals, numeric values, comments, and identifiers. This visual separation makes it far easier to scan a formatted query and spot logical sections, missing clauses, or copy-paste errors.

Yes. CREATE TABLE, ALTER TABLE, CREATE INDEX, DROP TABLE, and similar DDL statements are formatted with proper indentation for column definitions and constraints. INSERT with multi-row VALUES is also formatted cleanly.

No. All formatting runs entirely in your browser using JavaScript. Your SQL queries — including any sensitive schema or data details — never leave your machine.

Two-space indentation keeps queries compact, which is readable for short to medium queries. Four-space indentation provides stronger visual separation and is preferred for long analytical queries with many nested clauses. Both are widely accepted; teams usually standardize on one in their SQL style guide.
