Frequently asked questions
Which SQL dialects are supported?+
You can choose standard SQL, MySQL, PostgreSQL, SQLite, MariaDB, or BigQuery formatting, which adjust keyword handling and some dialect-specific syntax.
Does formatting change the meaning of my query?+
No, formatting only affects whitespace, line breaks, and keyword casing — the SQL logic and semantics remain identical to your original query.
Can this tool validate whether my SQL is correct?+
It performs light parsing needed for formatting, but it is not a full SQL validator. If your SQL has serious syntax errors, formatting may fail or produce unexpected output.
Why is keyword casing uppercase in the output?+
The formatter uppercases SQL keywords like SELECT, FROM, and WHERE by convention, since this is the most common professional style, though your original keyword casing in identifiers is preserved.
Is my SQL query sent to a server?+
No, formatting happens entirely in your browser using a JavaScript SQL formatting library — your queries and any table/column names in them never leave your device.
Can I format multiple statements at once?+
Yes, paste multiple semicolon-separated statements and the formatter will indent each one.
