You inherited a 200-line SQL query written as one continuous line. No indentation, no line breaks, aliases like "t1" and "t2". Understanding it will take an hour. Formatting it takes 2 seconds.
What Our Formatter Does
| Feature | Before | After |
|---|---|---|
| Indentation | Everything on one line | Proper nesting with 2/4 space indent |
| Keyword casing | select, SELECT, Select mixed | Consistent UPPERCASE or lowercase |
| Line breaks | None | Each clause on its own line |
| Comma placement | Trailing commas | Leading or trailing (your choice) |
| JOIN alignment | Inline with everything else | JOINs indented under FROM |

- Oracle — ROWNUM, CONNECT BY, PL/SQL blocks
- SQLite — simplified syntax, AUTOINCREMENT
Why Formatting Matters
Formatted SQL is not just prettier — it is debuggable. When a query returns wrong results, you need to read it. When a query is slow, you need to understand the join structure. When a colleague reviews your query, they need to follow the logic. All of this requires readable formatting.
Format your SQL — instant, free, multiple dialects.

According to Google SQL Style Guide, consistent formatting improves readability and maintainability of SQL code.
As SQL Style Guide by Simon Holywell recommends, keywords should be uppercase and each major clause should start on a new line.
