About this Tool
Format and beautify SQL queries with custom dialects, indentation, and casing.
1What is a SQL Formatter?
A SQL Formatter is a developer utility that parses unformatted database queries and formats them into aligned SQL statements. It supports SQL dialects like PostgreSQL, MySQL, SQLite, T-SQL, and PL/SQL. Formatting database queries is an essential developer workflow to improve readability in source control. The formatter operates client-side to keep secure schema tags private. Furthermore, the converter maintains exact data types for numbers, booleans, and null fields, ensuring type safety when importing files into database servers or runtime systems. The formatting layouts adhere strictly to official language specifications. With zero server round-trips required, developers can execute large translation tasks instantly without worrying about timeout thresholds, network latency, or upload speed bottlenecks.

2Example: Raw vs Formatted SQL
Input (Raw):
Output (Formatted):
select id,name,email from users where active=1 and role='admin' order by created_at desc limit 10;SELECT
id,
name,
email
FROM
users
WHERE
active = 1
AND role = 'admin'
ORDER BY
created_at DESC
LIMIT
10;3Supported SQL Dialects
Our SQL Formatter supports multiple relational database dialects, including:
• Standard SQL: Standard ANSI SQL formatting.
• PostgreSQL: Postgres-specific JSON operations and casts.
• MySQL / MariaDB: Backtick quoting and custom syntax.
• SQLite: Standard query parameters.
• Transact-SQL: SQL Server configurations.
4Keyword Casing & Indentation
Customize formatting output to match your company's style guide. You can enforce UPPERCASE keywords, lowercase keywords, or preserve original casing. Indentation can be configured to use 2-space, 4-space, or Tab character indentation.
5Minify SQL Queries
In addition to beautifying, you can minify SQL statements. Minification strips single-line and multi-line comments and condenses the SQL query into a single line. This is particularly useful for embedding queries in configuration files.
6Privacy: Your Queries Never Leave Your Browser
Database queries often contain sensitive schemas, table names, columns, or filter criteria. Because our SQL Formatter runs 100% client-side, your queries are processed locally. No SQL content is ever sent to a server, logged, or tracked.
Privacy Guarantee
The SQL Formatter & Beautifier operates 100% locally in your web browser. All code beautification, formatting, and side-by-side text comparisons are handled locally in your browser memory. Your source code files, configurations, and differences are kept private.
