SQL Formatter

Paste a SQL batch to expand keywords and clauses onto readable lines for code review and incident postmortems.

Result

Ready.

SQL readability for reviews and RCA

ORM debug logs arrive as one-line strings missing JOIN precedence cues. Reformatting before paste into a ticket prevents reviewers from misreading AND/OR binding and approving a risky migration.

Keyword casing

Consistent uppercase keywords (SELECT, WHERE, GROUP BY) scan faster in diffs. Teams can align style guides without arguing over manual line breaks during on-call handoffs.

Not a SQL linter

Invalid syntax may still format imperfectly. Pair this with database EXPLAIN and integration tests—layout alone does not catch missing indexes or implicit cartesian products.

FAQ

Which SQL dialects are supported?
Formatting targets common ANSI-style syntax shared by PostgreSQL, MySQL, and SQL Server. Vendor-specific constructs may not break lines exactly as your CLI formatter would.
Will this change query semantics?
No. Output is logically equivalent whitespace reshaping. Always run EXPLAIN on performance-critical statements—pretty layout does not imply a better plan.
Can I format stored procedures?
Large procedural blocks with nested BEGIN/END may format unevenly. Split batches or use dialect-specific tools for heavy PL/pgSQL or T-SQL bodies.
