A SQL formatter restructures raw or minified SQL queries with consistent indentation, keyword capitalization, and clause alignment so they are easy to read, review, and debug. Whether you are cleaning up auto-generated queries or reformatting legacy SQL before code review, this tool handles SELECT, INSERT, UPDATE, DELETE, CREATE, and ALTER statements.

How to Use the SQL Formatter
Raw SQL queries from ORMs, log files, or minified production code are hard to read. A SQL formatter restores structure and readability by applying consistent indentation, capitalized keywords, and properly aligned clauses. This is essential before code reviews, performance analysis, or debugging complex queries.
Step 1: Paste Your SQL
Copy your SQL query — however it arrives, as a single long line or multi-line raw text — and paste it into the input area. The tool accepts SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, and other standard SQL statements.
Step 2: Choose Indentation
Select your preferred indentation: 2 spaces for compact output or 4 spaces for wider column alignment. Click Format SQL to apply formatting immediately.
Step 3: Review and Copy
The formatted SQL appears on the right with keyword capitalization (SELECT, FROM, WHERE, JOIN) and structured indentation. Click Copy to place it on your clipboard, ready to paste into your editor, documentation, or code review tool.
SQL Formatting Best Practices
Consistent SQL formatting improves code review quality and query comprehension. Standard conventions: uppercase SQL keywords (SELECT, FROM, WHERE), each major clause on its own line, JOIN conditions indented under the JOIN keyword, and SELECT column lists with one column per line for complex queries. Well-formatted SQL is also easier to profile — the structure reveals which clauses might be causing performance bottlenecks.
FAQ
Is the SQL formatter free?
Yes, completely free with no signup required. Format unlimited SQL queries in your browser.
Is my SQL data safe?
Yes. All formatting runs locally in your browser. Your SQL queries are never sent to any server.
Which SQL dialects are supported?
The formatter supports standard SQL keywords used in MySQL, PostgreSQL, SQLite, and SQL Server including SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and JOIN syntax.
Does the formatter change my query logic?
No. The formatter only adjusts whitespace, indentation, and keyword capitalization. The query logic and output remain identical.
Can I format minified SQL?
Yes. Paste any SQL — whether a single long line or multi-line raw query — and the formatter will restructure it with consistent indentation and alignment.
