Format raw SQL with dialect support for SQL Server, MySQL, PostgreSQL, SQLite, and more.
The ByteKiln SQL Formatter applies dialect-aware formatting to your queries: uppercase keywords, consistent indentation, and proper line breaks between clauses. Your query is processed entirely in-browser — nothing is sent to a server.
Formatting standardizes keyword casing (SELECT, FROM, WHERE) and adds indentation so queries are easier to read in code reviews, documentation, and debugging sessions. Query logic is never changed.
Each SQL engine has slightly different conventions. Selecting MySQL, PostgreSQL, T-SQL, PL/SQL, or SQLite adjusts the output's keyword rules, spacing, and quoting style to match that engine's expected format.
No. The formatter is purely cosmetic — it only adjusts whitespace and casing. Table names, column names, values, and query logic remain completely untouched.
Short answers for the things developers usually ask before trusting a tool.
The formatter supports six dialects: Standard SQL, MySQL, PostgreSQL, SQL Server (T-SQL), PL/SQL (Oracle), and SQLite. Each dialect applies the correct keyword casing and syntax conventions for that database engine.
No. The formatter only adds whitespace and adjusts keyword casing. It never modifies table names, column names, query logic, or data values. The formatted output is semantically identical to the input.
Yes. Paste multiple statements separated by semicolons. The formatter processes each statement independently and adds blank lines between them for readability.
No. The ByteKiln SQL Formatter runs entirely in your browser. Your queries stay on your device and are never transmitted, stored, or logged anywhere.
While SQL keywords are case-insensitive in most databases, consistent casing (typically UPPER for keywords like SELECT, FROM, WHERE) makes queries significantly easier to read and review, especially in code reviews and documentation.
