From query spaghetti to readable SQL
SQL has a readability problem by design: it works exactly the same as one 400-character line or as forty indented ones — and production logs, ORM output and legacy code always pick the first option. Formatting is not cosmetics; it is how you see the joins, the nesting and the bug.
Dialects matter more than formatters admit: MySQL backticks, T-SQL brackets, PL/SQL idioms, BigQuery specifics. A formatter that parses real syntax — rather than splitting on keywords — puts clauses, subqueries and case expressions where they actually belong, in the dialect you are running.

How to use it
- Paste your SQL — one query or a multi-statement script.
- Pick the dialect: standard SQL, PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, PL/SQL or BigQuery.
- Choose keyword casing and indentation, then copy the formatted result.
Why this one
- Seven dialects plus standard SQL — real parsing, not regex keyword splitting.
- Keyword casing: upper, lower, or preserve the original.
- Multi-statement scripts formatted in one pass, up to 200k characters.
- Syntax errors surface with line and column.
Frequently asked questions
Does formatting change what my query does?
No. Formatting rewrites whitespace, line breaks and keyword casing only — the parsed statement is semantically identical. If the formatter cannot parse your SQL, it says so instead of guessing.
Which dialect should I choose?
The database the query actually runs against — dialects differ in quoting, functions and keywords. MySQL backticks are invalid in PostgreSQL; T-SQL brackets confuse everyone else. When unsure, standard SQL is the safe default.
Can it handle big generated queries?
Yes — inputs up to 200,000 characters, including multi-statement scripts separated by blank lines. ORM-generated monsters are the main use case.
