SQL Formatter
Paste any SQL query to format and beautify it with dialect-aware rules. Supports 13+ SQL dialects including MySQL, PostgreSQL, SQLite, BigQuery, Snowflake, SQL Server, Oracle PL/SQL, and more. Customize keyword casing and indentation. 100% client-side — your queries never leave the browser.
How It Works
Paste your SQL
Paste an unformatted or minified SQL query into the input panel. Multi-statement scripts are supported.
Pick dialect and style
Select your SQL dialect (MySQL, PostgreSQL, BigQuery, etc.), choose keyword casing, and pick an indentation width.
Copy the formatted output
The formatted query is produced instantly. Copy it with one click, or use the Minify button to collapse the input to a single line.
Frequently Asked Questions
Which SQL dialects are supported?
The tool supports Standard SQL, MySQL, PostgreSQL, SQLite, BigQuery, MariaDB, SQL Server (Transact-SQL), Redshift, Snowflake, Spark, Trino, DB2, and Oracle PL/SQL. Picking the correct dialect ensures dialect-specific keywords and syntax are preserved.
Is my SQL sent to a server?
No. All formatting happens entirely in your browser using JavaScript. Your queries never leave your device — safe to use on production credentials and sensitive schemas.
Can it format multiple statements at once?
Yes. Paste any number of semicolon-separated statements and each one will be formatted independently, with a blank line between statements.
What does keyword case do?
It controls how SQL keywords like SELECT, FROM, WHERE, and JOIN are capitalized. Choose UPPERCASE (convention), lowercase, or preserve the original casing of your input.
Does it validate my SQL?
The tool performs structural whitespace formatting but does not run full syntax validation. Most dialect-specific constructs are preserved, but invalid statements may still format without errors — use your database for actual syntax validation.
