A SQL formatter takes a dense, one-line or inconsistently written query and reformats it with clean line breaks, indentation and uppercase keywords so it is easy to read and review. This tool does it instantly in your browser, with nothing sent to a server.
How to use it
- Paste your SQL query.
- The formatted version appears with keywords on new lines and indented clauses.
- Copy the result back into your editor.
About SQL Formatter
SQL pulled from logs, ORMs or one-line scripts is often unreadable — a single long line with no structure. Formatting it reveals the query’s shape: which tables are joined, what the conditions are, and how subqueries nest. That makes reviewing, debugging and optimising far easier. This formatter uppercases keywords and breaks clauses onto their own lines following common conventions. It handles the most frequent statement types and runs entirely client-side, so queries containing sensitive table or column names stay private.
FAQ
Does it change my query’s meaning?
No. Formatting only adds whitespace and adjusts keyword casing. The query logic is unchanged.
Which SQL dialects are supported?
It formats standard SQL constructs common to MySQL, PostgreSQL, SQL Server and SQLite. Highly vendor-specific syntax may format imperfectly.
Is my query uploaded?
No. Formatting happens entirely in your browser.
