Frequently Asked Questions
Which database dialects are supported?
MySQL, PostgreSQL, SQLite, T-SQL, MariaDB, BigQuery, Snowflake, and other common database dialects.
Will my SQL be sent to a server?
No. All formatting happens locally in the browser, and your SQL never leaves the device.
Does formatting change the SQL logic?
No. Formatting only adjusts whitespace, line breaks, and indentation; it does not change the statement's semantics or execution result.
Does it support minifying SQL?
It currently supports beautifying. If you need to minify, copy the result and remove line breaks manually, or use another tool.
