Example 1: Minified SQL vs Beautified SQL

Minified SQL

Copy
SELECT id,name,age,email FROM users WHERE status='active' AND (signup_date>='2023-01-01' OR last_login IS NOT NULL) ORDER BY signup_date DESC,name;

Beautified SQL

Copy
SELECT
    id,
    name,
    age,
    email
FROM
    users
WHERE
    status = 'active'
    AND (
        signup_date >= '2023-01-01'
        OR last_login IS NOT NULL
    )
ORDER BY
    signup_date DESC,
    name;

Example 2: Minified SQL with multiple statements vs Beautified SQL

Minified SQL

Copy
INSERT INTO orders(id,user_id,amount,created_at)VALUES(1023,45,159.99,'2024-06-05 14:22:00');UPDATE inventory SET quantity=quantity-1 WHERE product_id=77;

Beautified SQL

Copy
INSERT INTO
    orders (
        id,
        user_id,
        amount,
        created_at
    )
VALUES
    (
        1023,
        45,
        159.99,
        '2024-06-05 14:22:00'
    );

UPDATE inventory
SET
    quantity = quantity -1
WHERE
    product_id = 77;

Customization options

Below are the settings you can adjust to get the exact SQL output you want after formatting.

Option Default Description
SQL Dialect SQL Target dialect such as MySQL PostgreSQL SQLite TSQL and others so the formatter handles dialect specific constructs
Indent Size 4 Number of spaces used per indent level in the formatted output
Use Tabs False When true use tab characters for indentation instead of spaces
Keyword Case Uppercase Set case for SQL keywords such as SELECT FROM and WHERE. Options include Uppercase Lowercase Preserve
Type Case Preserve Set case for data types. Preserve keeps the input case
Function Case Preserve Set case for function names such as COALESCE or CONCAT
Identifier Case Preserve Set case for identifiers such as column and table names
AND OR Break Before Control whether logical operators appear on a new line before or after the operator
Wrap Width 50 Maximum characters before wrapping long expressions or lists into multiple lines
Tight Operators False When enabled remove extra spaces around operators for denser output
Semicolon Break False When enabled place the semicolon on a new line after each statement

Why use this SQL beautifier and formatter

Consistent SQL formatting reduces friction in query review and keeps diffs small in version control. When queries follow the same structure they are faster to scan easier to debug and less likely to introduce errors which improves review throughput and overall SQL quality.

Use this SQL beautifier and formatter to standardize queries across teams and repositories and to streamline handoffs between developers and DBAs. Format SQL queries before reviews or integrate the tool into your build or pre commit process to keep history clean and speed up onboarding.

Best practices and workflow

  • Agree on indent size casing and wrapping rules for your project to avoid noisy diffs
  • Run the SQL formatter in pre commit hooks so queries stay consistent at commit time
  • Combine formatting with a linter to catch potential syntax or performance issues early
  • Keep reusable functions and views organized to simplify formatting and reuse
  • Store formatted SQL in version control and generate minified scripts during deployment

Conclusion

Use this SQL beautifier and formatter to make queries clearer and easier to maintain. It runs in the browser with no setup and offers flexible options so you can produce formatted SQL with your own preferences.
