SQL Formatter & Beautifier

How to Format SQL Online

Paste your SQL query into the input box on the left. Select your database dialect and formatting preferences from the options bar, then click Format SQL — or just start typing and the formatter runs automatically. The output panel shows clean, readable SQL with proper indentation and consistent keyword casing, ready to copy back into your editor or query tool.

Supported SQL Dialects

This formatter supports MySQL, PostgreSQL, SQLite, T-SQL (SQL Server), Standard SQL, and BigQuery. Selecting the correct dialect ensures dialect-specific keywords and functions are recognized and formatted correctly. For example, PostgreSQL supports :: casting syntax and RETURNING clauses, while T-SQL uses TOP instead of LIMIT.

SQL Formatting Best Practices

Practice	Why It Matters
Uppercase keywords	Visually separates SQL keywords from identifiers and values, improving scan-ability
One clause per line	SELECT, FROM, WHERE, JOIN each on their own line makes diffs cleaner and logic easier to follow
Consistent indentation	Nested subqueries and conditions are much easier to trace with 2 or 4 space indentation
Alias with AS	Explicit AS keyword makes column and table aliases unambiguous and self-documenting
Avoid SELECT *	Explicit column lists prevent unexpected columns in results and improve query performance
