Privacy: Your SQL is formatted entirely in your browser. The query never leaves this page.

## About

Minified or hand-written SQL is hard to read and easy to get wrong. A few seconds of formatting turns a dense one-liner into a clearly indented, skimmable query that you can debug, review, and share with confidence.

This formatter understands the grammar of the major SQL dialects — MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, and T-SQL — so keywords, joins, and subqueries are indented correctly for each. The entire formatting step runs in your browser; your queries stay private.

## How to use

1. **Paste your SQL** — Any query, however messy — the formatter handles one-liners and minified code.
2. **Pick your dialect** — Select the database flavor so reserved words and syntax are handled correctly.
3. **Tune and copy** — Toggle keyword uppercase or tab indentation, then copy the cleaned query.

## Examples

### A messy one-liner becomes readable

Formatting separates the columns, tables, and conditions onto their own lines.

Input:

```
select id,name from users where id=1 and active=true order by name desc
```

Output:

```
SELECT
  id,
  name
FROM
  users
WHERE
  id = 1
  AND active = true
ORDER BY
  name DESC
```

## FAQ

### Is my SQL sent to a server?

No. Formatting happens entirely in your browser using the sql-formatter library. Your query, which may contain sensitive schema details, never leaves the page.

### Which dialects are supported?

Generic SQL plus MySQL, PostgreSQL, SQLite, MariaDB, BigQuery, and T-SQL. Pick the closest match to your database for the most accurate formatting.

### Does it validate my SQL?

No — it is a formatter, not a validator. It will format syntactically incorrect SQL too, but the output makes errors much easier to spot.
