Format and beautify SQL queries with proper indentation and line breaks.
This free SQL formatter instantly beautifies messy, minified, or hard-to-read SQL queries into clean, well-indented code. Whether you're debugging a complex JOIN, reviewing a colleague's query, or preparing SQL for documentation, this tool makes your code readable in one click.
SQL formatting is the process of restructuring a SQL query with consistent indentation, line breaks, and keyword capitalization to improve readability. Raw SQL — especially when generated by ORMs or copied from logs — is often written on a single line with inconsistent spacing, making it nearly impossible to understand at a glance.
A well-formatted SQL query separates each clause onto its own line, indents subqueries and nested conditions, and capitalizes reserved keywords like SELECT, FROM, WHERE, and JOIN. This makes the logic of the query immediately clear, reduces debugging time, and helps teams collaborate more effectively on database code.
This tool supports all major SQL dialects including MySQL, PostgreSQL, Microsoft SQL Server, Oracle, and SQLite. The formatting rules are dialect-agnostic, so the output works across platforms without modification.
Formatting your SQL is straightforward with this tool. Here's how to get started:
Always format SQL before sharing it in code reviews or documentation. Unformatted SQL is one of the most common sources of confusion in database-heavy projects. A few seconds of formatting can save hours of misunderstanding.
Use the "Uppercase Keywords" option consistently across your team. Capitalizing SQL keywords like SELECT, FROM, and WHERE makes them visually distinct from table names, column names, and aliases, which dramatically improves readability in complex queries.
When working with long SELECT lists, enable the "Comma on New Line" option. This makes it easy to add, remove, or comment out individual columns without disrupting the rest of the query. It also makes version control diffs much cleaner.
Unlike IDE plugins that require installation and configuration, this tool works instantly in any browser with no setup. It's perfect for quick formatting tasks when you're working on a machine that doesn't have your usual development environment set up.
The tool is completely free with no usage limits, no account required, and no ads interrupting your workflow. It handles queries of any size and complexity, from simple SELECT statements to multi-page stored procedures with nested subqueries and CTEs.
Your privacy is our priority. All processing happens entirely in your browser using JavaScript. No files, data, or inputs are ever uploaded to any server. Everything stays on your device, making this tool completely safe to use with sensitive content.
