SQL Formatter

Format and beautify SQL queries — uppercase keywords, indent subqueries, break lines before major clauses. Handles SELECT, INSERT, UPDATE and CREATE TABLE.

Why These Tools

SQL pasted from a log file is unreadable. Keywords are lowercase, clauses run together, and a five-line query becomes a single unbroken string. The SQL Query Formatter & Beautifier reads that string and returns something a developer can follow: major clauses on their own lines, keywords uppercased, subqueries indented one level. It tokenizes properly, preserving string literals, comments and qualified names without mangling them.

A visual query builder and a JOIN visualizer are next in this category. Each one runs entirely in the browser, so nothing you paste is sent to a server.
