What the SQL Formatter Does

Every formatting option you need to turn unreadable SQL into clean, maintainable code.

✏️

Keyword casing

Choose UPPERCASE, lowercase or Title Case for all SQL keywords. SELECT, FROM, WHERE — all consistent.

↔️

Proper indentation

Nested clauses indented consistently with 2 spaces, 4 spaces or tabs. Readable at a glance.

📐

Clause separation

Each major clause — SELECT, FROM, WHERE, JOIN — starts on its own line. No more wall-of-text queries.

🔗

JOIN formatting

JOIN conditions aligned and clearly separated from the main query body.

📋

VALUES rows

Each INSERT row on its own line. Large INSERT statements become easy to scan and edit.

🗜️

SQL minifier

Remove all whitespace and comments to produce a compact single-line query for production use.

💬

Comment preservation

Single-line (--) and block (/* */) comments are preserved in the formatted output.

🌐

6 SQL dialects

MySQL, PostgreSQL, SQLite, SQL Server, Oracle and generic SQL all supported.

Why Format SQL?

Readable SQL is Maintainable SQL

Unformatted SQL is one of the most common sources of bugs in database-heavy applications. When a query is written on a single line with no indentation, it is nearly impossible to spot a missing JOIN condition, a wrong column reference or a logic error in a WHERE clause.

Properly formatted SQL makes the structure visible. Each clause on its own line, consistent indentation, and uppercase keywords make it easy to read, review and debug — whether you wrote it or inherited it from someone else.

When to use the SQL formatter

Before committing SQL to version control
When reviewing a query written by someone else
After copying SQL from a log file or error message
When debugging a complex query with multiple JOINs
Before sharing SQL in documentation or a code review

Before → After

-- Before (unformatted)
select u.id,u.name,o.total from users u inner join orders o on u.id=o.user_id where u.status='active' and o.total>100 order by o.total desc limit 10
-- After (formatted)
SELECT
    u.id, u.name, o.total
FROM users u
INNER JOIN orders o ON u.id = o.user_id
WHERE u.status = 'active'
    AND o.total > 100
ORDER BY o.total DESC
LIMIT 10;

FAQ

Common Questions

Does the formatter change my SQL logic?

No. The formatter only changes whitespace, indentation and keyword casing. It never modifies the logic, column names, table names or values in your query.

What is the difference between Format and Minify?

Format adds indentation and line breaks to make SQL readable. Minify does the opposite — it removes all whitespace and comments to produce a compact single-line query, useful for embedding in application code.

Does it support stored procedures and functions?

The formatter handles most DDL and DML statements including CREATE PROCEDURE and CREATE FUNCTION blocks. Very complex procedural SQL may need manual review.

Can I format multiple SQL statements at once?

Yes. Paste multiple statements separated by semicolons and the formatter will handle each one correctly, with a blank line between statements in the output.

Does it preserve my comments?

Yes. Both single-line comments (-- comment) and block comments (/* comment */) are preserved in the formatted output.

Is there a query length limit?

No hard limit. The formatter runs entirely in your browser and handles queries of any length. Very large blocks of SQL may take a moment to process.
