SQL Formatter
Beautify and format SQL queries for readability.
Frequently asked questions
Does this actually parse the SQL, or just reformat the text?
Just text reformatting — it works off a fixed list of known keywords (SELECT, FROM, WHERE, JOIN, and similar) that get uppercased and pushed onto new lines. It doesn't understand SQL structure, so if one of those words happens to appear inside a string literal or comment, it gets reformatted too, whether or not it's actually part of the syntax.
How does it decide where to break lines?
A fixed set of clause keywords — SELECT, FROM, WHERE, the JOIN variants, ORDER BY, GROUP BY, HAVING, LIMIT, and UNION — each start a new line, and commas get their own line break with a two-space indent, which is what spreads out a column list or VALUES list.
Will it work on any SQL dialect?
It only recognizes common ANSI-style keywords, so it's dialect-agnostic in that sense, but it doesn't specifically know vendor extensions — anything outside its keyword list is just left untouched rather than rejected.
