What is an SQL Formatter?

An SQL Formatter is a tool that takes raw, messy, or minified SQL queries and automatically adds proper indentation, line breaks, and capitalization to make the code highly readable.

Which SQL dialects are supported?

Our advanced formatter supports standard SQL, MySQL, PostgreSQL, SQLite, MariaDB, and SQL Server (T-SQL).

Is my SQL data sent to a server?

No. All SQL formatting is done locally in your browser using JavaScript. Your queries and database structures are never uploaded to any external server.

Why Use an SQL Formatter?

Writing SQL queries is a daily task for backend developers, data analysts, and database administrators. While writing a simple SELECT statement is easy, complex queries involving multiple JOINs, GROUP BY clauses, and nested subqueries can quickly become a messy block of text.

An SQL Formatter (or Beautifier) takes that unreadable block of code and structures it perfectly. It automatically applies logical line breaks, standardized indentations, and consistent capitalization to SQL reserved keywords.

Features of ToolVigo's SQL Beautifier

Multi-Dialect Support: Not all databases use the exact same syntax. Our tool supports formatting rules specific to MySQL, PostgreSQL, SQLite, and Microsoft SQL Server (T-SQL).
Custom Casing: Most developers prefer SQL keywords (like SELECT, FROM, WHERE) to be capitalized for readability. You can choose between UPPERCASE, lowercase, or preserving your original typing style.
Instant Live Formatting: No need to reload the page or submit forms. Click "Format SQL" and the beautifully structured code appears instantly in the output panel.
100% Secure & Private: SQL queries often contain sensitive database schema information (like table and column names). Because our formatter runs entirely on Client-Side JavaScript, your code is never transmitted over the internet to our servers.
