Format and Beautify Complex SQL Queries Locally
Unformatted SQL queries generated by ORMs or pasted from server logs are hard to inspect, debug, and optimize. Proper query indentation and capitalized SQL keywords make complex JOINs, window functions, and nested subqueries immediately readable.
TabKit SQL Formatter beautifies and indents queries across PostgreSQL, MySQL, SQLite, Oracle, and MS SQL dialects. Because execution occurs entirely client-side, proprietary database table schemas, internal column names, and confidential queries remain completely private.
The formatting parser aligns SELECT statements, GROUP BY clauses, and ORDER BY directives with consistent column indentations for effortless team peer review.
Clean SQL Conventions
- UPPERCASE Keywords: SELECT, FROM, WHERE, GROUP BY, HAVING, ORDER BY, LIMIT
- Leading Comma Style: Simplifies line commenting and git diff review
- Explicit JOIN Syntax: Prefer INNER/LEFT JOIN over implicit WHERE table1, table2
- CTE Readability: Use WITH expressions over deeply nested inline subqueries
Multi-Dialect Compatibility
The formatting engine handles dialect-specific clauses gracefully, including PostgreSQL ON CONFLICT DO UPDATE, MySQL ON DUPLICATE KEY, and SQLite upsert semantics without breaking valid syntax.
Frequently Asked Questions
Which SQL dialects are supported?
Standard ANSI SQL, PostgreSQL, MySQL, SQLite, and Microsoft SQL Server query syntaxes are supported.
Will formatting alter the query execution logic?
No. Formatting modifies only whitespace, indentation, and keyword casing without altering SQL statement semantics or table logic.
Are my confidential SQL queries uploaded to any server?
Never. All formatting executes 100% locally in your web browser. No queries are stored or transmitted.
