SQL Formatter & Beautifier

Why Use an Online SQL Formatter?

Database queries often become unreadable over time. When developers export SQL from application logs, ORMs (like Prisma or Hibernate), or performance monitoring tools, the queries are typically minified onto a single line. Our SQL Formatter instantly parses these massive, messy queries and applies standard indentation, capitalizes keywords, and aligns clauses (like SELECT, FROM, WHERE, and JOIN).

Supported SQL Dialects

Different database engines use slightly different syntax and proprietary keywords. This tool supports dialect-specific formatting to ensure accurate parsing:

• PostgreSQL: Supports standard Postgres syntax, including advanced JSONB operators and window functions.
• MySQL & MariaDB: Accounts for backtick identifiers and MySQL-specific functions.
• SQL Server (T-SQL): Supports Transact-SQL specific keywords like NOLOCK, TOP, and bracket identifiers.
• SQLite: Perfect for mobile developers and lightweight database configurations.

Is this secure?

Yes. Queries containing sensitive data (like user emails, password hashes, or financial records) should never be sent to a remote server for formatting. This formatter runs 100% inside your web browser. It uses the open-source sql-formatter library to process the query locally on your machine, ensuring zero data leakage or telemetry.
