About SQL Formatter

Why format SQL?

Readable SQL is easier to review, debug and maintain. This formatter puts major clauses (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY) on their own lines and indents conditions and column lists.

What it does

It normalises keyword casing to uppercase, breaks the query into logical lines, and indents AND/OR conditions and selected columns so the structure is clear at a glance.

Scope

It's a lightweight client-side beautifier ideal for SELECT/INSERT/UPDATE/DELETE statements. For dialect-specific linting, pair it with your database's own tools.

Frequently asked questions

Does it change my query's meaning?

No — it only adjusts whitespace and keyword casing, never the logic.

Which SQL dialects are supported?

It works with standard SQL clauses common to MySQL, PostgreSQL, SQL Server and SQLite.

Is my SQL sent anywhere?

No. Formatting happens locally in your browser.
