How to use it
- Paste your SQL into the input box. A long single line query is fine.
- Press Format, or just keep typing, the output updates live as you go.
- Read the cleaned up query in the output box and press Copy to grab it.
How the formatter works
The formatter does three simple, reliable things to make SQL easier to read. First, ituppercases the standard keywords such as SELECT, FROM,WHERE, JOIN and GROUP BY, which is the usual SQL convention and makes the shape of a query easy to scan.
Second, it puts the major clauses on their own lines. Keywords that start a new section of a query, like FROM, WHERE, the JOIN variants, GROUP BY,ORDER BY, HAVING, LIMIT and UNION, are moved to a fresh line so the structure lines up vertically.
Third, it indents the column list in a SELECT, placing each comma separated item on its own indented line, and it collapses runs of extra whitespace so nothing looks cramped or ragged.
A clean format, not a full parser
This is a fast, readable formatter rather than a complete SQL parser. It focuses on layout and casing and does a great job on everyday queries, but it does not understand every dialect specific quirk or deeply nested edge case. Treat the result as a tidy starting point and always review it before running the query. Because everything runs locally, your SQL is never uploaded, which keeps table names and data private.

Which dialects work?
Standard keywords shared across MySQL, PostgreSQL, SQL Server, SQLite and more.
