Why Format SQL Queries?
Unformatted SQL queries — especially those generated by ORMs, copied from logs, or written in a single line — are extremely hard to read and debug. A SQL formatter adds proper indentation, line breaks, and keyword highlighting to make complex queries understandable at a glance.

SQL Formatting Best Practices
- Put each major clause (SELECT, FROM, WHERE, JOIN) on its own line
- Indent column lists and conditions for readability
- Use UPPERCASE for SQL keywords and lowercase for table/column names
- Align JOIN conditions with the JOIN keyword
- Break long WHERE clauses into multiple lines with AND/OR at the start
