Frequently Asked Questions
Does this formatter validate SQL syntax?▼
No, this is a formatting tool, not a SQL validator. It reformats your SQL for readability but does not check whether the query is syntactically correct or will execute successfully. It preserves your SQL logic exactly as-is.
Which SQL dialects are supported?▼
This formatter works with standard SQL (ANSI SQL) and is compatible with MySQL, PostgreSQL, SQLite, SQL Server, and Oracle queries. It formats based on common keywords and structure rather than dialect-specific syntax.
Are my queries safe?▼
Yes, absolutely. All formatting happens in your browser. Your SQL queries are never sent to any server, logged, or stored. This makes it safe to format queries containing sensitive table names, credentials, or business logic.
What does minify do?▼
Minify removes all unnecessary whitespace, line breaks, and comments from your SQL query, compressing it into a single line. This is useful for embedding SQL in code, reducing payload size in API requests, or logging queries more compactly.
