It supports standard SQL along with common syntax from MySQL, PostgreSQL, SQLite, and SQL Server. Most everyday queries format cleanly across these dialects. Because vendors add their own functions and extensions, very unusual or proprietary syntax may not format perfectly, but the core statements and clauses are handled well regardless of which database you are targeting.

No. The formatter only adjusts whitespace, line breaks, indentation, and keyword case. It never reorders clauses, changes conditions, or alters the logic, so your query returns exactly the same results before and after formatting. This makes it completely safe to format production queries you simply want to read more easily without any risk of changing their behavior.

Yes. The formatter handles all standard statement types including SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER, and more. For multi-row inserts it lays out the value groups clearly, and for CREATE statements it indents column definitions so the schema is easy to read. This is helpful when reviewing migration scripts or schema changes before applying them.

Uppercasing keywords like SELECT, WHERE, and JOIN while keeping table and column names in their normal case is a long-standing readability convention. It visually separates the language structure from your data, so the shape of the query is obvious at a glance. SQL itself is not case-sensitive about keywords, so this is purely about making queries easier for humans to read and review.

No. It improves formatting but does not validate syntax, check that tables and columns exist, or analyze performance. A query can be perfectly formatted and still contain logic errors or run slowly. Use the formatter to make a query readable, then rely on your database client or an EXPLAIN plan to confirm correctness and efficiency before running it on real data.

Yes, and it is one of the most popular uses. Queries assembled as concatenated strings in code often arrive as one long line with awkward spacing. Paste that into the formatter to instantly see the readable structure, which makes it much easier to verify the logic, spot a missing space or join condition, and document the query properly in a pull request.

Yes. All formatting happens locally in your browser using JavaScript, so the SQL you paste is never sent to a server or stored anywhere. This makes the tool safe to use with queries that reference internal table names or sensitive schema details. Once the page has loaded it also works offline, since formatting does not require any server connection.
