SQL Formatter

The SQL Formatter pretty-prints a SQL statement with keyword-aware indentation, which turns a wall of text into a structure you can review in seconds. It knows SELECT, FROM, JOIN, WHERE, GROUP BY, and the other major clauses, so it places each on its own line and indents subqueries and set operations consistently. The result runs identically, because whitespace between keywords is insignificant in SQL. Use it when you are writing long queries, reviewing a colleague, or debugging a messy script that you pasted from a log. SQL is whitespace insensitive, which means a query can be written on one line and still be perfectly valid, and that is exactly why unformatted queries are so hard to read. Keywords form the skeleton of a statement, and placing each clause such as SELECT, FROM, JOIN, WHERE, GROUP BY, and ORDER BY on its own line with consistent indentation turns a wall of text into something you can review top to bottom. Subqueries and set operations are where formatting helps most, because nested structure becomes visible at a glance and a misplaced parenthesis or a predicate in the wrong clause stands out immediately. The output is identical in behaviour to the input, since only the whitespace between tokens has changed, so you can format a query, run it, and compare results without any risk of altering the logic. This is most useful when you are reviewing a long query someone else wrote, when a statement was pasted out of a log or a ORM debug output, or when you want a consistent house style across a team.
