Frequently Asked Questions
- Is my SQL sent to a server?
- No. All formatting runs in your browser using a pure TypeScript implementation. Your query never leaves your device.
- Which SQL dialects does it support?
- The formatter works with standard SQL and most popular dialects including MySQL, PostgreSQL, SQLite, and SQL Server. It uppercases keywords and indents clauses — it does not parse or validate dialect-specific syntax.
- Does it validate SQL?
- No. This is a formatter, not a validator. It applies keyword uppercasing and clause indentation without parsing the query semantically. Syntax errors in the input will still appear in the output.
- What SQL statements are supported?
- SELECT, INSERT INTO, UPDATE, SET, DELETE FROM, CREATE TABLE, ALTER TABLE, DROP TABLE, WITH (CTEs), and UNION/UNION ALL. All common clauses — WHERE, JOIN variants, GROUP BY, ORDER BY, HAVING, LIMIT, OFFSET — are also handled.
