SQL Formatter: Format & Beautify SQL Queries Online | Free Tool

A Yes, our formatter correctly handles JOINs, subqueries, CTEs (WITH clauses), UNION, GROUP BY, HAVING, and all standard SQL clauses.

A Yes, paste multiple SQL statements separated by semicolons and they will all be formatted.

A Yes, completely free with no usage limits. Your SQL never leaves your browser — all processing is done locally.

A Absolutely. Your privacy is paramount. When you paste your SQL query into our formatter, all processing happens directly within your web browser. Your SQL code never leaves your device and is not sent to any server. This ensures complete confidentiality and security for your sensitive database queries, making it a safe choice for any SQL task without data exposure concerns.

A Absolutely! Our SQL Formatter includes a "Minify SQL" option specifically designed for this. It condenses your multi-line query into a single, compact line by removing all unnecessary whitespace, line breaks, and comments. This is incredibly useful for embedding SQL within application code, configuration files, URLs, or logs where space efficiency and a single-line format are crucial, without altering the query's functionality.

A Most likely it's your indentation settings. Try switching between 2-space, 4-space, or tab indentation to match your team's style guide. Keyword case also matters — upper or lower can change the visual weight significantly. Our tool defaults to 4 spaces and uppercase keywords, but you can tweak both. For a quick fix, set keyword case to match your existing codebase before formatting.

A Yes, it handles most vendor-specific syntax out of the box. MySQL's backtick quoting, PostgreSQL's dollar-quoted strings, and SQL Server's square brackets all work fine. The formatter recognizes over 200 SQL keywords across dialects. One thing it won't do is validate your syntax against a specific database engine. For example, you can format Oracle PL/SQL blocks with BEGIN...END just fine. If you hit a weird edge case with a proprietary function, try formatting it anyway — odds are 90% it'll work.

A Not after the first load. The tool loads once from our CDN, then runs entirely in your browser's JavaScript engine. You can disconnect from WiFi right after the page finishes loading and still format SQL offline. All 200+ SQL keywords are baked into the script. Bookmark the page for quick access without typing the URL again.

A Our tool changes appearance only, not the logic. If your original query had a missing comma or mismatched parentheses, formatting won't fix that. The formatter rearranges whitespace and capitalizes keywords, but it never rewrites your syntax. I've seen people paste invalid SQL, get it looking clean, then waste 20 minutes debugging the same typo. Always test the formatted version against your database before calling it done.

A No, it never changes the dialect. If you paste T-SQL with square brackets, you'll get T-SQL with square brackets back. The formatter only adjusts whitespace, indentation, and keyword casing. Think of it like a code prettier, not a translator. I've had users paste MySQL and expect it to come out as PostgreSQL, but that's a different tool entirely. For dialect conversion, you'd need something like SQLines or a manual rewrite.
