SQL Formatter

SQL Formatter & Beautifier — Free Database Query Prettifier

Format, beautify, and indent SQL queries (ANSI, PostgreSQL, MySQL, SQLite) directly in your browser. Built on client-side SQL lexers, this tool formats complex subqueries locally without exposing database structures remotely.

Standards & Specifications

• ANSI SQL Standard: Standard database query clause keywords (SELECT, FROM, WHERE, JOIN, GROUP BY).
• Dialect Support: PostgreSQL, MySQL, SQLite, T-SQL, Oracle SQL syntax patterns.

How to Format SQL Queries Step-by-Step

1. 1Paste Raw SQL Query: Input unformatted database scripts into the editor.
2. 2Select SQL Dialect: Choose ANSI SQL, PostgreSQL, MySQL, or SQLite.
3. 3Click Format SQL: Indent clauses and capitalize SQL keywords automatically.
4. 4Copy Formatted SQL: Copy clean SQL queries to clipboard.

Practical Database Use Cases

• Query Optimization: Prettify complex multi-table JOIN subqueries to improve code readability.
• Code Reviews: Standardize SQL formatting across team pull requests and documentation logs.

Standardized Developer Tools & Cryptographic Utilities

Modern web development and software engineering require reliable, secure utilities for formatting JSON payloads, inspecting JWT authentication tokens, encoding Base64 data strings, and generating cryptographically secure UUIDs and hashes.

Our suite of developer tools is built strictly to comply with RFC and IETF internet standards.

Technical & Cryptographic Compliance:

• RFC Standards Compliance: Adheres to RFC 8259 (JSON), RFC 7519 (JWT), RFC 4122 (UUID v4), and RFC 4648 (Base64).
• Native Web Crypto API Integration: Uses hardware-accelerated, cryptographically secure pseudo-random number generators (CSPRNG) and SHA/MD5 hashing algorithms.
• Client-Side Security: Secrets, API keys, JWT tokens, and private database queries are processed entirely inside browser memory, ensuring development credentials are never exposed over network logs.
