SQL copied from logs, ORM debug output or chat messages is often squeezed into one line and hard to read. Paste it here to get neatly formatted SQL: SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING, LIMIT, UNION, INSERT, VALUES, UPDATE, SET and DELETE each start a new line, column lists go one per line, AND / OR conditions break and align, JOINs are indented, and subqueries and CASE expressions are indented by depth. The tokenizer understands strings, comments, double-quoted / backtick / bracket identifiers and PostgreSQL dollar-quoted strings, so their contents are never altered. Keywords can be upper-cased, lower-cased or kept, with 2 / 4 space or tab indentation, and you can minify to a single line with comments removed. Multiple statements are supported.

## How to use

1. Paste SQL, including multiple statements and comments
2. Choose Format or Minify and set keyword case and indentation
3. Copy the formatted SQL on the right

- Strings, comments and quoted identifiers preserved
- Keyword case: UPPER, lower or keep
- 2 / 4 spaces or tab indentation
- Minify to one line and strip comments
- Works with common MySQL, PostgreSQL, SQL Server and SQLite syntax, locally

## FAQ

### Can formatting change what my query does?

No. Only whitespace, line breaks and keyword case change; strings, identifiers and comments are left as-is. Minify mode removes comments, which does not affect execution.

### Which SQL dialects are supported?

It uses generic SQL rules that fit MySQL, PostgreSQL, SQL Server, SQLite and Oracle, recognizing backtick and bracket identifiers, :: casts, ->> JSON operators and $1 / ? / :name placeholders. Complex DDL such as stored procedures may get only basic layout.

### Why did a column name become upper-case?

Column names that are also SQL keywords (date, text, rank …) are treated as keywords when changing case. Choose Keep to leave casing alone, or quote such identifiers.

### Is my data uploaded?

No. Everything runs locally in your browser with no network upload and is discarded when you close the page, so it is safe for internal or sensitive data.
