About the Sql
Format and beautify SQL queries online for free. Paste minified or messy SQL from logs, ORMs, or tickets and get a readable, properly indented query - instantly and privately, with all formatting done in your browser.
Minified or hand-written SQL quickly becomes unreadable: long JOIN chains, nested subqueries, and dense WHERE clauses hide bugs and make code review harder. A formatted query makes missing conditions, Cartesian joins, and logic errors visible at a glance.
Paste any SQL statement to format and beautify it with standard indentation, respecting keywords, subqueries, and CTEs. Works with SELECT, INSERT, UPDATE, DELETE, and DDL statements from PostgreSQL, MySQL, SQLite, and SQL Server dialects.
Use cases and examples
Decode the wall of SQL an ORM generates: paste the logged query, format it, and finally see which joins and conditions are driving the cost.
Clean up queries before pasting them into code review, documentation, or a ticket so reviewers read logic instead of noise.
Prepare a query for optimization work - a formatted statement makes it far easier to reason about join order and predicates.
How to use
- Paste your SQL query into the editor.
- The formatted query appears instantly with clean indentation.
- Review the readable version to spot logic issues.
- Copy the beautified SQL back into your code or ticket.
