Format SQL queries with uppercase keywords, proper indentation, and clear line breaks.
Format SQL queries with uppercase keywords, proper indentation, and clear line breaks.
Paste your SQL query into the input area and click "Format SQL." The tool converts SQL keywords to uppercase, adds line breaks before major clauses, and indents sub-clauses for readability. The result is a clean, professional query layout that is easy to read, review, and debug.
SQL queries often start simple but grow complex with joins, subqueries, and conditions. Unformatted SQL crammed onto one line is difficult to understand and error-prone to modify. Properly formatted SQL with each clause on its own line, consistent keyword casing, and indented conditions makes the query logic immediately visible. This is crucial for code reviews, documentation, and debugging.
This formatter handles standard SQL syntax that works across MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. It recognizes common keywords and clause structures used in all major database systems. While dialect-specific extensions may not be specially handled, the general formatting improves readability for any SQL variant.
Your SQL queries are formatted entirely in your browser. No data is sent to any server, making this tool safe for queries containing sensitive table names, column data, or business logic.
