What does an SQL formatter do?
An SQL formatter (or beautifier) rewrites queries with consistent indentation, line breaks, and often standardized keyword capitalization so SELECT, FROM, and JOIN blocks are easy to scan. It does not change query meaning for well-formed input; it is primarily a readability and code-review aid for analysts, backend engineers, and DBAs pasting snippets from logs, ORMs, or one-off scripts.
How this SQL Formatter works
Dynamic Duniya’s SQL Formatter uses the open-source sql-formatter package directly in your tab. Paste messy or minified SQL, select the dialect that matches your database engine (the dropdown lists every dialect the library supports), choose whether SQL keywords appear in UPPER, lower, or preserved case, and pick indentation with 2 spaces, 4 spaces, or tabs. Click Format to generate pretty-printed SQL in the output panel. Identifiers, function names, and data types are left as in your source unless you change keyword casing — the tool preserves them by design.
Why dialect matters
Different engines accept slightly different syntax — string quotes, dollar-quoting, backticks, JSON operators, and procedural blocks. Choosing the closest dialect helps the parser produce sensible layout and fewer parse errors. If you are unsure, try generic “sql” or switch dialects until formatting succeeds.
Privacy
Formatting runs entirely client-side. Your queries are not uploaded to Dynamic Duniya for processing. Avoid pasting production secrets on shared computers; use Clear when finished.
