SQL Formatter

Anyone who has scrolled through a 400-character SQL query jammed onto a single line knows the pain this tool solves. A stored procedure export, a query copied from a Slack thread, or a minified statement pulled from an application log often arrives with no line breaks, inconsistent capitalization, and clauses packed together in a way that makes it nearly impossible to spot a missing JOIN condition or a misplaced parenthesis. The SQL Formatter takes that raw text and rebuilds it into a properly indented, readable query so you can actually see its structure — SELECT list, FROM, WHERE, GROUP BY, and nested subqueries each landing on their own visually distinct block.

Paste or type a query and the formatter parses its clauses and reflows them with consistent indentation and alignment, breaking long SELECT lists and multi-condition WHERE clauses onto separate lines rather than leaving them as one dense run of text. It's built to handle the dialect differences that trip up generic beautifiers, covering MySQL, PostgreSQL, SQL Server, and Oracle syntax so quoting conventions and dialect-specific keywords aren't mangled in the process. This makes it useful for cleaning up deeply nested subqueries, multi-table JOINs, and CTEs where poor formatting hides logic errors rather than just looking untidy.

Because everything runs client-side in your browser, the query text never leaves your machine — there's no upload step and nothing to sign up for, which matters when the SQL you're formatting contains internal table names, business logic, or anything else you'd rather not paste into a third-party server. A common workflow is formatting a query before a code review or before adding it to a migration file, since consistent indentation makes diffs in version control far easier to read than one squashed onto a single line.
