How it works
Your SQL is parsed and re-printed with consistent indentation, keyword casing and line breaks using the open-source sql-formatter library, loaded and run in your browser.
100% client-side — nothing you paste is ever uploaded.
Frequently asked questions
Which SQL dialects are supported?
Standard SQL, PostgreSQL, MySQL, SQLite, BigQuery and SQL Server (T-SQL). Pick the one that matches your database for the most accurate formatting.
Is my query sent anywhere?
No. Formatting happens entirely in your browser, so it's safe to paste sensitive queries.

What is the best SQL formatter?
There is no single best one; it depends on where you work. For quick paste-and-copy jobs, a browser tool like this page, built on the open-source sql-formatter library, handles most dialects with no install. Inside an editor you usually want the formatter that integrates there: Prettier with a SQL plugin in VS Code, the built-in reformatter in DataGrip, or Beautify Query in MySQL Workbench. Whichever you choose, make sure it understands your dialect so it does not mangle dialect-specific syntax.
How can I beautify MySQL code?
Paste the query here and choose MySQL as the dialect; the formatter normalizes keyword casing, puts each clause on its own line and indents subqueries. If you are already in MySQL Workbench, select the query and use Edit > Format > Beautify Query to do the same thing. Formatting only changes whitespace and keyword case, so the query runs exactly as before.
Can Notepad++ beautify SQL?
Not out of the box; Notepad++ only highlights SQL syntax. You can add formatting through Plugins > Plugins Admin, where community plugins such as Poor Man's T-SQL Formatter add a Format SQL command. If you would rather not install anything, paste the query into an online formatter like this one and copy the result back.
How to use an SQL formatter?
Paste or type your query into the input box, pick the SQL dialect that matches your database (MySQL, PostgreSQL, SQL Server and so on), and the formatted version appears with consistent keyword casing, line breaks and indentation. Copy the output back into your editor or query tool. The formatter changes only whitespace and letter case, never the logic, so the result is safe to run.
What are the 5 basic SQL commands?
The five commands most tutorials start with are SELECT (read rows), INSERT (add rows), UPDATE (change existing rows), DELETE (remove rows) and CREATE (make a table or other object). Together with clauses like WHERE, JOIN, GROUP BY and ORDER BY, they cover the vast majority of everyday queries. Formatting tools like this one recognise these keywords and use them as the anchors for line breaks and indentation.
How do I format an SQL query?
The usual convention is to write keywords in uppercase, start each major clause (SELECT, FROM, WHERE, GROUP BY, ORDER BY) on its own line, indent the items that belong to a clause, and put each joined table and each condition on a separate line. Doing this by hand is tedious, so most people paste the query into a formatter like this one, which applies those rules automatically for the chosen dialect.
