ツールの紹介

Turn dense SQL into a readable, consistently indented layout with one clause per line, uppercased keywords, and aligned JOINs and subqueries.

ツール概要

A well-formatted SQL query reads like a paragraph, not a wall of words. This tool tokenizes your statement, places each major clause (SELECT, FROM, WHERE, GROUP BY, ORDER BY, JOIN) on its own line, indents subqueries and CTE bodies, and uppercases standard keywords. It keeps quoted identifiers, string literals, and inline comments untouched. Works with PostgreSQL, MySQL, SQLite, SQL Server, and ANSI SQL.

ユースケース

Clean up SQL pasted from logs or ORMs before reviewing it in a PR.
Standardize team query style without installing a CLI formatter.
Make a complex CTE chain readable for documentation or onboarding.

よくある質問

Will it modify my data or run the query?+

No. The tool only reformats the text. Nothing is executed against any database.

Does it support PostgreSQL-specific syntax?+

Yes. ::casts, $$ dollar-quoted strings, RETURNING, ON CONFLICT, and JSONB operators are recognized and preserved.

Can it format multiple statements at once?+

Yes. Statements separated by semicolons are formatted independently and joined with a blank line between them.
