Frequently Asked Questions
Does this formatter modify my table or column names?
No. The formatter only adjusts whitespace, line breaks, and SQL keyword capitalization. Table names, column aliases, schema names, and WHERE conditions are left completely intact.
Are string values and comments inside the SQL query safe?
Yes. The tokenizer isolates all single-quoted string literals and comment blocks before formatting and restores them verbatim, ensuring no words inside quotes are accidentally capitalized.
Which database dialects are supported?
The engine supports standard ANSI SQL as well as PostgreSQL, MySQL, MariaDB, SQLite, Microsoft SQL Server (T-SQL), and Oracle.
Are my confidential database queries sent to any external server?
No. All lexing and formatting executes 100% client-side in your local browser memory. Zero queries are logged or sent across any network.
