How to pretty-print a SQL statement

1. Paste the SQL

   Drop a `SELECT`, `INSERT`, `UPDATE`, `DELETE`, or DDL statement into the "SQL" field. Most major dialects work — Postgres, MySQL, SQLite, MS SQL — though dialect-specific syntax (window-frame `ROWS BETWEEN`, `JSON_VALUE`, …) is kept verbatim, not normalised.

2. Press Run

   Result returns a single `formatted` field. Keywords go uppercase (`SELECT`, `FROM`, `JOIN`, `WHERE`), columns indent under `SELECT`, joins land on their own line, and `AND` / `OR` chains break under `WHERE`.

3. Comments and strings

   Single-line (`-- …`), block (`/* … */`), and Postgres `--` style comments pass through. String literals (`'foo'`) and quoted identifiers (`"col"`, `` `col` ``) are never touched — content inside them is treated as opaque.

4. What it doesn't change

   No query rewriting, no optimisation hints, no schema validation. If your query reorders joins or alters parens, that's the formatter making cosmetic spacing choices — the semantics never shift.
