Is the SQL formatter free?

Yes, completely free with no signup required.

Are my queries kept confidential?

Completely. The sql-formatter library runs in your browser only — queries containing table names, schema details, or embedded values are never sent to any server.

Which SQL dialects are supported?

Standard SQL, MySQL, PostgreSQL, SQLite, T-SQL (SQL Server / Azure), and BigQuery are all supported.

Does formatting change my query?

No. The formatter only adds whitespace and capitalises keywords. It never changes identifiers, values, or query logic.

Can I format multiple statements?

Yes. Paste multiple SQL statements separated by semicolons and all will be formatted.

How to Format SQL Online

1
Paste your SQL
Paste a raw or minified SQL query into the input box. One or more statements are supported.
2
Choose a dialect
Select the SQL dialect that matches your database (MySQL, PostgreSQL, etc.) for accurate keyword handling.
3
Copy the formatted SQL
Click Format and copy the output. The query is formatted with consistent indentation and capitalised keywords.

SQL gets unreadable faster than almost any other language: a query joins a few tables, grows a subquery and a CASE expression, and suddenly it is a 400-character line that no one wants to review. Because SQL ignores whitespace entirely, formatting is pure presentation — the formatter can be aggressive about layout with zero risk of changing what the query returns.

Dialect awareness matters:each database has its own syntax quirks — PostgreSQL's ::casts, MySQL's backtick identifiers, T-SQL's bracketed names and TOP, BigQuery's backtick-quoted project paths. Pick your dialect before formatting so these constructs are laid out correctly instead of being treated as syntax errors.

Where formatted SQL pays off: code review (a formatted query diffs line-by-line, so reviewers see exactly which JOIN or WHERE clause changed), debugging (indentation makes subquery boundaries and JOIN order visible at a glance), and rescuing queries copied from ORMs, logs, or legacy reports that arrive as one line.

A note on what it is not: a formatter does not lint or optimise — it will happily format a slow query beautifully. Treat it as the readability step before analysis. If your workflow also involves moving query results around, the CSV to Excel and JSON formatter tools cover the common output formats.
