SQL Formatter
Turn dense SQL into clean, readable queries — with keyword casing, indentation and clause alignment across 10 dialects. Formatting happens in place.
What it does
The formatter splits your query at clause boundaries (SELECT / FROM / WHERE / GROUP BY / ORDER BY),
indents subqueries and JOIN ... ON expressions, normalizes comma lists, and standardizes
keyword casing. It runs on the widely-used sql-formatter engine, entirely in your browser.
Every action applies to the current editor content — chain Format → change dialect → Format again,
and Undo always takes you one step back.
FAQ
Will formatting change my query's meaning?
No — whitespace and casing of unquoted identifiers do not affect SQL semantics. String literals and quoted identifiers are preserved exactly.
Can it handle multiple statements?
Yes, semicolon-separated statements are formatted one after another.
Is my SQL uploaded?
No. Formatting runs entirely in your browser — safe for proprietary schemas.
