What is SQL Formatter?

SQL Formatter is a developer tool that takes messy, single-line, or poorly indented SQL queries and reformats them into clean, readable code. It uppercases SQL keywords (SELECT, FROM, WHERE, JOIN), adds proper newlines between clauses, indents columns and subqueries, and highlights syntax in the output. It also includes a minify option to collapse formatted SQL back to a single line for use in code or scripts.

How to Use SQL Formatter

1
Paste your SQL
Enter or paste your SQL query into the input area. It can be messy, single-line, or already partially formatted.
2
Click Format
Press Format SQL or Ctrl+Enter to beautify the query with proper indentation and keyword uppercasing.
3
Or minify
Click Minify to collapse the SQL to a single compact line, useful for embedding in code.
4
Copy the result
The output includes syntax highlighting. Click Copy to get the plain-text formatted SQL.

Features

Automatic SQL keyword uppercasing
Clause separation (SELECT, FROM, WHERE, GROUP BY, etc.)
JOIN statement indentation
AND/OR logic operator indentation
SELECT column list formatting
Syntax highlighting with color-coded keywords, strings, and numbers
One-click minify to single line
Works with SELECT, INSERT, UPDATE, DELETE, CREATE and more

Frequently Asked Questions

Which SQL dialects does it support?+

The formatter works with standard SQL syntax that is common across PostgreSQL, MySQL, SQLite, SQL Server, and Oracle. Dialect-specific syntax is preserved as-is.

Does it validate my SQL?+

No, this tool only formats SQL. It does not check for syntax errors or execute queries. Use your database client for validation.

Can it format stored procedures or PL/SQL?+

The formatter handles standard DML and DDL statements. Complex procedural code with IF/ELSE blocks, loops, or variable declarations may not be formatted optimally.

Does it handle subqueries?+

Yes, subqueries are detected via parentheses and formatted with appropriate indentation. Deeply nested subqueries will have progressive indentation.

What about comments in SQL?+

Single-line comments (--) and block comments (/* */) are preserved in the output. They may shift position slightly due to reformatting.

Can I format multiple statements at once?+

Yes, paste multiple statements separated by semicolons. Each statement will be formatted independently.

Is my SQL sent to a server?+

No. All formatting happens in your browser using JavaScript. No data is transmitted anywhere.

What is the minify option for?+

Minify collapses your SQL to a single line with minimal whitespace. This is useful when embedding SQL in code strings, URLs, or log messages where multi-line formatting is impractical.
