How to Use
Paste a SQL query into the editor and the formatted version appears automatically. I usually load an ORM-generated query, format it, and then scan for missing joins or incorrect filters before troubleshooting further.
- Paste your SQL query into the input area.
- Review the formatted output on the right.
- Copy the formatted SQL if you need to share or save it.
- Repeat as you iterate on the query.
Use Cases
SQL formatting helps when:
- Debugging ORM output to see the real query shape.
- Reviewing migrations where readable SQL avoids mistakes.
- Sharing queries with teammates during reviews.
- Optimizing performance by making joins and filters obvious.
Tips & Best Practices
Format before reviews
Consistent formatting makes diffs smaller and code reviews faster.
Keep column lists readable
Splitting columns onto new lines helps spot typos in long SELECT clauses.
Verify logic blocks
Indented AND/OR clauses make it easier to confirm boolean logic.
Use comments for clarity
Add inline comments after formatting to explain complex joins.
