# SQL Formatter & Query Beautifier

Format complex SQL queries with keyword uppercasing and dialect support for PostgreSQL, MySQL, SQLite, and Transact-SQL.

## What is SQL Formatter & Query Beautifier?

Turn dense, unreadable SQL queries into structured, standardized code. Formats SELECT, JOIN, WHERE, and GROUP BY clauses with uppercase keyword standardization and multi-dialect compatibility (PostgreSQL, MySQL, SQLite, T-SQL).

## How to use SQL Formatter & Query Beautifier

1. **Add your file or input** — Choose a supported file, drag it onto the upload area, or type/paste the data this tool works with.
2. **Adjust the options** — Pick the output format, quality, size or other settings the tool offers. Defaults work well for most files.
3. **Process and download** — Run the tool and save the result. Processing happens in your browser, so nothing is uploaded to a server.

## Frequently asked questions

### Which SQL dialects are supported by the formatter?

Standard ANSI SQL, PostgreSQL, MySQL, MariaDB, SQLite, Microsoft SQL Server (T-SQL), and Oracle PL/SQL syntax are all cleanly formatted.

### Can the tool capitalize all SQL reserved keywords automatically?

Yes! The uppercase keyword feature standardizes commands like SELECT, FROM, WHERE, INNER JOIN, and ORDER BY while preserving original case on table and column names.

### Is my database query structure kept private?

Yes. Formatting runs locally using in-browser tokenizers. No query schemas, table structures, or proprietary SQL logic are ever sent over the network.
