How to Use SQL Formatter

  1. Paste your messy or minified SQL query into the input editor.
  2. Choose your database dialect (Standard SQL, PostgreSQL, MySQL, SQLite, MariaDB, Transact-SQL).
  3. Toggle uppercase keywords and customize your preferred indentation width (2 or 4 spaces).
  4. Copy the formatted query or download it as a .sql file with one click.

Practical Examples

Complex JOIN & Aggregation Formatting

Beautifies multiple joins, WHERE conditions, and GROUP BY clauses.

Input:
SELECT u.name, o.id FROM users u JOIN orders o ON u.id = o.user_id WHERE u.active = 1
Output:
SELECT
  u.name,
  o.id
FROM
  users u
  JOIN orders o ON u.id = o.user_id
WHERE
  u.active = 1

Common Mistakes & Troubleshooting

  • Selecting the wrong dialect: Dialects like PostgreSQL and MySQL have distinct quoting rules (double quotes vs backticks). Select your specific database dialect from the dropdown for the cleanest output.
  • Pasting incomplete SQL statements: FormatFlow beautifies fragments, but mismatched parentheses may report syntax warnings.

Frequently Asked Questions

Does this SQL formatter execute queries against my database?

NO. FormatFlow is strictly a client-side text formatter. It never establishes database connections or sends queries to external servers.

Which SQL dialects are supported?

We support Standard ANSI SQL, PostgreSQL, MySQL, SQLite, MariaDB, Transact-SQL (SQL Server), PL/SQL (Oracle), and BigQuery.
