SQL Formatter & Minifier
Sobre SQL Formatter & Minifier
Our free online SQL Formatter & Minifier reorganizes your SQL queries so major clauses like SELECT, FROM, WHERE, and JOIN each sit on their own line with consistent indentation - making complex queries far easier to read and debug.
It works with standard ANSI SQL keywords shared across MySQL, PostgreSQL, SQL Server, and SQLite. Everything runs in your browser, so your queries and table/column names are never uploaded anywhere.
Who Uses This Tool
Backend developers use it to clean up a long auto-generated or copy-pasted query before reviewing it in a pull request. Database administrators use it to reformat a slow query pulled from logs so the clause structure is easier to reason about while tuning it. Data analysts writing ad hoc reporting queries use it to keep multi-join statements readable instead of one dense line. Students learning SQL use the formatted output to see how a working query is actually broken into clauses. Because the formatter works from shared ANSI SQL keywords rather than a specific database engine's proprietary syntax, it is a safe general-purpose cleanup step regardless of which database the query will eventually run against.

Frequently asked questions
Which SQL dialects does this support?
It works with standard ANSI SQL keywords (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, etc.) shared across MySQL, PostgreSQL, SQL Server, and SQLite - it doesn't validate dialect-specific syntax.
Does this validate my SQL query?
No - it reformats keyword placement and indentation for readability, it doesn't parse or execute the query, so it won't catch logical or syntax errors.
Is my SQL sent to a server?
No - formatting and minifying happen entirely in your browser; your queries (and any table/column names in them) are never uploaded.
