SQL Formatter Online

What Is SQL Formatting?

SQL formatting changes the layout of a SQL query so it is easier to read. Keywords, clauses, joins and conditions are placed on separate lines or with clearer spacing. The goal is to improve readability without changing the query you wrote.

Why Format SQL Queries?

Long SQL queries are often hard to read when they come from logs, applications, database tools or copied text. Formatting makes the structure easier to see. It can help you find joins, filters, grouping and ordering before you use the query again.

How to Use the SQL Formatter

1. Paste your SQL query into the input box.
2. Select the SQL dialect that matches your query.
3. Choose indentation and keyword case if needed.
4. Click Format SQL.
5. Copy or download the result.

The Query Inspector also shows basic information such as statement count, joins, CTEs and common clauses. It does not run your query.

SQL Formatting Example

Before formatting, a query may be written on one long line:

select u.id,u.name,count(o.id) as order_count from users u left join orders o on o.user_id=u.id where u.status='active' group by u.id,u.name order by u.name;

After formatting, the same query is easier to scan:

SELECT
    u.id,
    u.name,
    COUNT(o.id) AS order_count
FROM users u
LEFT JOIN orders o
    ON o.user_id = u.id
WHERE u.status = 'active'
GROUP BY u.id, u.name
ORDER BY u.name;

Choosing the SQL Dialect

SQL syntax is not identical across database systems. Choose MySQL, PostgreSQL, SQL Server, SQLite or Standard SQL to match the query you are formatting. If the selected dialect does not match the query, formatting may fail or the result may not match your expectations.

When SQL Formatting Does Not Work

First check the selected dialect. Then check the query for incomplete statements, unusual database-specific syntax or unsupported features. The original text in the input box is not replaced when formatting fails.

Version 1.0 does not support stored procedures or custom statement delimiters.

What Does Minify SQL Do?

Minifying removes unnecessary whitespace and comments to make a query more compact. It is useful when you need a shorter representation of a query. Minifying is a layout operation; it does not execute the SQL.

What Does the Query Inspector Show?

The Inspector provides simple structural information from the text you entered, such as the number of statements, SELECT clauses, joins, subqueries, CTEs, WHERE clauses, GROUP BY and ORDER BY clauses. It is not an execution-plan analyzer and it does not connect to your database.

Is My SQL Uploaded?

The formatter and Inspector run in your browser. The tool does not need to send your SQL query to iToolsEra for formatting. Even so, avoid pasting passwords, private keys or other sensitive data into any online tool unless your security policy allows it.
