SQL Formatter
Format messy SQL into readable, consistently indented queries. Great for debugging joins, sharing snippets, and reviewing migration scripts.
Why Use a SQL Formatter?
Unformatted queries are hard to audit and easy to misread. A formatter makes query logic clearer by separating SELECT fields, JOIN clauses, WHERE filters, and ORDER BY groups.
For API payload cleanup, pair this with our JSON Formatter. For XML output from older systems, use the XML Formatter.
When to Format SQL
- Before code reviews: Clean queries are easier to reason about and catch logic mistakes in.
- During incident response: Quickly spot incorrect joins, missing filters, or malformed conditions.
- Before sharing in tickets: Structured SQL helps teammates reproduce and troubleshoot faster.
What This Formatter Does
This formatter normalizes whitespace, applies keyword case, and introduces line breaks for common clauses. It is intended for readability and quick debugging, not full SQL linting or execution planning.
FAQ
Does this execute my SQL?
No. It only reformats text in your browser and never runs queries.
Is this ANSI-SQL strict?
No. It is a practical formatter for common SQL patterns and is not a full parser for every dialect edge case.
Can I keep lowercase keywords?
Yes. Use the lowercase toggle and then run formatting to preserve that style consistently.
Will this validate table or column names?
No. It does not connect to a database and cannot verify schema correctness.
