Free Online SQL Formatter & Beautifier
Format, beautify, and minify SQL queries online. Supports MySQL, PostgreSQL, SQLite, T-SQL dialects. Adjustable indentation, keyword case, and one-click copy.
What is a SQL Formatter?
A SQL Formatter automatically restructures raw or minified SQL queries into clean, readable code. It adds consistent indentation, aligns clauses (SELECT, FROM, WHERE, JOIN), and optionally normalizes keyword casing. This makes it much easier to review, debug, and share complex queries — especially those generated by ORMs or copied from logs.
How to Use the SQL Formatter
- Paste your SQL query into the input area on the left.
- Choose your SQL dialect (MySQL, PostgreSQL, SQLite, T-SQL, or Generic) from the dropdown.
- Select indentation style (2 spaces, 4 spaces, or tab) and keyword casing (UPPERCASE or lowercase).
- Click Format to beautify or Minify to compress. Then copy the result with one click.
SQL Formatter Features
- Multi-dialect support: MySQL, PostgreSQL, SQLite, T-SQL, and Generic SQL
- Configurable indentation: 2 spaces, 4 spaces, or tab characters
- Keyword case normalization: UPPERCASE, lowercase, or preserve original

- 100% browser-based — SQL is processed locally, never sent to a server
SQL Formatter FAQ
Does formatting change the SQL behavior?
No. Formatting only changes whitespace and keyword casing. The logical structure, table names, column names, and values are never modified, so the formatted SQL executes identically to the original.
Which SQL dialects are supported?
MySQL, PostgreSQL, SQLite, T-SQL (SQL Server), and a Generic mode that works for standard ANSI SQL. Dialect selection affects how certain keywords and syntax are interpreted during formatting.
Can I format multiple statements at once?
Yes. Paste multiple SQL statements separated by semicolons and the formatter will process them all, preserving statement boundaries.
