SQL Formatter is a 100% free, browser-based utility that enables you to format sql queries for mysql, postgresql and more. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the SQL Formatter
Long SQL queries written on a single line are hard to review. The SQL Formatter rewrites them with each clause (SELECT, FROM, JOIN, WHERE, GROUP BY…) on its own line, consistent indentation and your choice of upper- or lower-case keywords.
Pick the SQL dialect you use, including MySQL, PostgreSQL, SQL Server (T-SQL), SQLite, Oracle PL/SQL, BigQuery, Snowflake and more, so dialect-specific syntax is handled correctly.
How to use the SQL Formatter
- Paste your SQL query into the input box.
- Choose your SQL dialect, keyword case and indentation.
- Copy the formatted SQL or download it as a .sql file.
Features
- 15+ SQL dialects
- UPPER / lower keyword case

Frequently asked questions
Does the formatter change what my query does?
No. It only changes whitespace, line breaks and keyword capitalisation. Identifiers, strings and logic are left untouched.
Why choose a dialect?
Databases differ in syntax such as quoting identifiers (backticks in MySQL, brackets in SQL Server), parameter placeholders and special operators. Selecting the right dialect helps the formatter parse your query correctly.
Is it safe to paste production queries?
Yes. Formatting happens entirely in your browser and the query is never sent to a server or database.
