SQL Formatter
Format SQL queries so long statements become readable, with major clauses on their own lines and consistent capitalization of keywords. A dense SELECT with several joins and a nested WHERE is hard to reason about on one line, and reformatting it makes the logic obvious before you run it against a database. This formatter uppercases standard keywords, breaks before clauses like FROM, WHERE, JOIN, GROUP BY and ORDER BY, and indents join and condition lists so structure is visible. It is aimed at everyday analytical and application queries. Paste your SQL, click format, and copy the tidy version into your editor or migration. All formatting stays in your browser, so query text and schema names are never uploaded.
How to use SQL Formatter
- Paste your cramped SQL query.
- Click format to align keywords and clauses.
- Copy the readable SQL.
