SQL Formatter and Beautifier Formatted SQL is easier to read in code review, easier to debug, and communicates intent clearly. A dialect-aware formatter handles the syntax differences between MySQL, PostgreSQL, SQLite, and MSSQL automatically. The SQL standard (ISO/IEC 9075) defines the base language, while each database's documentation covers extensions: PostgreSQL documentation, MySQL reference manual. --- Why SQL Formatting Matters Unformatted SQL is hard to reason about: The same query formatted: Formatted SQL makes the intent visible at a glance: which tables are joined, which conditions filter the result, and how results are ordered.

Frequently Asked Questions
How do I format a SQL query?
Paste your SQL into a formatter, select your dialect (MySQL, PostgreSQL, SQLite), choose keyword casing (uppercase or lowercase), and click Format. The formatter tokenizes your query and reconstructs it with consistent indentation and spacing.
What SQL formatter options are available?
Common options include keyword casing (UPPER/lower), identifier quoting (double quotes vs backticks), indentation size (2 or 4 spaces), comma position (leading or trailing), and line break location (before or after keywords like SELECT and FROM).
How do I set keyword casing in SQL?
Most formatters have a keyword case option: uppercase (SELECT, FROM, WHERE), lowercase (select, from, where), or preserve original. The community is split; uppercase keywords are the historical standard and improve readability when identifiers are lowercase.
What is the best online SQL formatter?
sql-formatter (the npm library) supports the widest range of dialects including MySQL, PostgreSQL, SQLite, MSSQL, BigQuery, Spark SQL, and Trino. Browser-based tools using this library format instantly without sending your queries to a server.
How do I format SQL in VS Code?
Install the SQL Formatter Plus or SQLTools extension. Add a `.editorconfig` entry for `.sql` files or use the extension's settings to configure dialect, indentation, and keyword casing. Run Format Document (Shift+Alt+F) to format.
