Frequently Asked Questions
What SQL dialects are supported by the SQL Formatter?
This formatter parses standard ANSI SQL queries, which is compatible with major databases like PostgreSQL, MySQL, SQLite, MariaDB, Microsoft SQL Server, and Oracle.
What is SQL minification?
Minification removes all unnecessary spaces, comments, and line breaks from your SQL query, reducing its character size to make it compact for pasting into CLI commands or application code.
Are my database queries private?
Yes, absolutely. The entire formatting and parsing process is done with client-side Javascript. No network requests are made, keeping your database structures completely private.
Quick reference

| Major clauses on new lines | SELECT / FROM / WHERE / GROUP BY / ORDER BY |
| Keyword case | UPPERCASE keywords, identifiers untouched |
| JOIN placement | Each JOIN…ON pair on its own line |
Interpretation guide
| Why format SQL | Benefit |
|---|---|
| Code review | Diffs show logic changes, not whitespace |
| Debugging | Clause-per-line isolates the failing predicate |
| Team style | Consistent layout across authors |
Formula & methodology
Formula: Tokenise → uppercase keywords → break before major clauses → indent continuation lines
- Paste any SQL — single statements or scripts.
- The formatter tokenises the query, uppercases keywords, and starts each major clause on its own line with consistent indentation.
- Copy the result back into your codebase.
Worked example: select id,name from users u join orders o on o.uid=u.id where o.total>100 order by o.total desc becomes a six-line, clause-aligned query where the JOIN condition and filter are instantly visible.
