Frequently Asked Questions

What SQL statements does this formatter support?

The formatter handles all common SQL statements including SELECT, INSERT INTO, UPDATE, DELETE FROM, CREATE TABLE, ALTER TABLE, and DROP. It also properly formats JOINs (INNER, LEFT, RIGHT, FULL OUTER, CROSS), subqueries, CASE/WHEN expressions, UNION, GROUP BY, ORDER BY, and window functions.

How does the keyword highlighting work?

The formatter tokenizes your SQL and applies color coding: SQL keywords appear in cyan, string literals in green, numbers in orange, comments in gray, and identifiers (table/column names) in white. This makes queries much easier to read and debug.

Does this tool support different SQL dialects?

The formatter uses standard ANSI SQL keywords that work across all major databases including MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. While dialect-specific syntax is preserved, the formatting focuses on universally recognized SQL keywords and clauses.

Is my SQL data secure when using this tool?

Yes. All formatting and processing happens entirely in your browser using client-side JavaScript. Your SQL queries are never sent to any server, ensuring complete privacy for sensitive database queries.

What is the difference between beautify and minify?

Beautify adds proper indentation, line breaks, and uppercases keywords to make SQL readable and maintainable. Minify removes all unnecessary whitespace and comments to compress the query into a single line, useful for embedding in code or reducing payload size.
