SQL Formatter
Format a SQL query onto clean, readable lines with capitalized keywords, or minify it back down — instantly inside your browser.
Why format SQL?
SQL queries are often written or generated as one long line, which makes them hard to read and debug — especially with several JOINs, conditions, or a long SELECT list. This tool breaks major clauses onto their own lines, indents nested conditions, and capitalizes SQL keywords for consistency.
GuideHow to use it
How the formatting works
Recognized SQL keywords like SELECT, FROM, WHERE, JOIN, and ORDER BY are capitalized and each major clause starts on its own line, with AND/OR conditions indented beneath WHERE, and comma-separated columns split onto their own lines. This is a keyword and pattern-based formatter rather than a full SQL parser, so it works well on typical queries but may not perfectly handle every edge case in complex, deeply nested SQL.
Why it helpsFeatures & benefits
Why this runs entirely in your browser
SQL queries can contain sensitive table names, column names, or literal data, so formatting runs in JavaScript locally in the tab, and nothing pasted here is ever sent to a server.
Common uses
Making a machine-generated or minified query readable for code review, cleaning up a query before pasting it into documentation, or quickly reformatting a query copied from a database GUI.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
It formats based on common ANSI SQL keywords shared across MySQL, PostgreSQL, SQLite, and SQL Server, so it works well for typical queries across dialects.
No. Formatting only changes whitespace, line breaks, and keyword casing — the underlying query logic is never altered.
No. This is a formatter, not a SQL parser or validator — it won't catch syntax errors in your query.
It handles typical queries well, but as a pattern-based formatter rather than a full parser, very complex or deeply nested SQL may not format exactly as a dedicated SQL IDE would.
No. All formatting happens locally in your browser. Nothing pasted here is sent to a server, stored, or shared.
