How to use it

Apply lightweight SQL formatting by normalizing whitespace, putting major clauses on new lines and placing comma-separated items on separate lines.

Paste SQL into the input area.
Select Format.
Review and copy the reformatted SQL.

Major clauses: SELECT, FROM, WHERE, GROUP BY, ORDER BY, JOIN, UNION and related keywords
Commas: Line break inserted after commas
Quoted strings: Single- and double-quoted strings temporarily protected
Parser: No SQL dialect parser or syntax validation

A one-line SELECT becomes a readable clause layout

SELECT id, name FROM users WHERE active = 1 ORDER BY name; is split so SELECT, FROM, WHERE and ORDER BY begin on separate lines, with selected columns separated after commas.

This is a simple text formatter. Comments, vendor-specific syntax and complex procedural SQL are not parsed semantically, so always review the result before using it in production.

Quoted strings are protected during keyword rewriting

Single- and double-quoted string literals are temporarily replaced with placeholders so SQL words inside them are less likely to be treated as clauses.

Whitespace is normalized before line breaks are added

Runs of whitespace are collapsed, then recognized major keywords are moved to fresh lines. Existing manual indentation is not preserved.

Commas always trigger a new line in the simple formatter

The formatter does not distinguish SELECT lists from function arguments using a full parse tree, so comma-heavy expressions can be reformatted more aggressively than a dedicated SQL formatter.

Formatting does not prove that SQL is valid

No database engine or SQL parser is called. A query with a syntax error can still be neatly formatted.
