A SQL query dumped from an ORM's debug log usually comes out as one dense, barely readable line, and a multi-table JOIN with several conditions genuinely needs consistent indentation to actually follow which clause belongs to which part of the query, a structure that's invisible once everything gets flattened onto a single line. This tool formats and indents SQL queries with keyword highlighting and a customizable style, turning a dense query back into something with visible structure rather than one unreadable line.
