How to Use the SQL Formatter

Formats SELECT, INSERT, UPDATE, DELETE, CREATE, and JOIN statements. Keywords are uppercased, commas start new lines, and parentheses are indented.

What is SQL Formatter?

A MySQL formatter (also called SQL beautifier) indents and structures raw SQL queries for readability. It standardizes keyword casing, adds consistent spacing, and makes complex queries easier to review and debug.

Common Uses

  • Formatting SQL before committing to version control
  • Cleaning up auto-generated ORM output
  • Debugging long nested queries during code reviews

Why use Aya Corporation?

Your SQL queries may contain table names, column values, and sensitive schema details. Aya Corporation formats entirely client-side — nothing is sent to any server.

When to use

Before committing SQL to version control, during code reviews, when debugging long nested queries, or cleaning up auto-generated ORM output.

Notes from this implementation

Whitespace only, not a rewrite

The formatter breaks a SQL statement onto lines and indents clauses it recognizes (SELECT, FROM, WHERE, JOIN, and the usual list). It does not choose indexes, and it should not change string literals or quoted identifiers. A formatter that lowercases keywords is a style choice; a formatter that changes a literal is a bug.

Dialects differ. Backticks, RETURNING, and LIMIT are not universal. If the indented result no longer parses, the original was using a construct this indenter split in the wrong place, often a comma inside a function call. Keep the original in the other half of the screen until the database accepts the formatted text.
