How do I format a SQL query?

Paste your SQL query into the input textarea and click the 'Format' button. The formatted SQL appears instantly in the output panel. You can also press Ctrl+Enter (or Cmd+Enter on Mac) to format. Adjust indentation and keyword case using the options above the output.

Does the formatter support all SQL dialects?

The formatter handles standard SQL syntax including SELECT, FROM, WHERE, JOIN variants, GROUP BY, ORDER BY, HAVING, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER, and more. It works well with MySQL, PostgreSQL, SQLite, and other major SQL dialects. Dialect-specific functions are left as-is.

Can I choose between 2-space and 4-space indentation?

Yes. Use the indentation toggle in the options bar to switch between 2 spaces and 4 spaces per indent level. The output updates immediately when you change this setting.

What does the uppercase keywords toggle do?

When enabled, all SQL keywords (SELECT, FROM, WHERE, JOIN, etc.) are automatically converted to uppercase in the formatted output. When disabled, keywords keep their original case. This is useful for maintaining consistent coding style across your team.

Does the formatter preserve string literals and comments?

Yes, the formatter recognizes single-quoted strings and does not modify their contents. Comments (lines starting with -- or enclosed in /* */) are preserved as-is in the formatted output.

Can I minify SQL instead of formatting it?

While the primary purpose is beautification, you can achieve a minified result by copying the original unformatted input. The formatter is designed to add structure and readability to SQL code.

Is my SQL data secure?

Absolutely. All formatting happens client-side in your browser. Your SQL queries are never sent to any server, stored, or tracked. You can safely format queries containing sensitive table names, column names, or business logic.

What do the keyword count and line count stats mean?

The keyword count shows how many SQL keywords (SELECT, FROM, WHERE, etc.) were found in your query. The line count shows the total number of lines in the formatted output. These stats help you understand the complexity and size of your SQL query.

Can I use the Swap button?

Yes. The Swap button moves the formatted output into the input textarea, allowing you to re-format with different settings or make manual adjustments. This is useful when you want to tweak the formatting options and re-run the formatter.

Does the tool work with very long SQL queries?

Yes. The formatter handles queries of any length. Since it runs in your browser, performance depends on your device, but it easily formats queries with hundreds of lines and complex nested subqueries.

100% Private — Your SQL Never Leaves Your Browser

All SQL formatting happens entirely in your browser. No queries are sent to any server, stored, or tracked.

How to Use the SQL Formatter

Paste your SQL — Enter or paste a SQL query into the input textarea. You can click "Load Sample" to try the tool with a complex example query containing JOINs, WHERE clauses, and GROUP BY.
Choose options — Select 2-space or 4-space indentation, and toggle the "Uppercase Keywords" option to control whether SQL keywords are automatically uppercased in the output.
Format — Click the "Format SQL" button or press Ctrl+Enter (Cmd+Enter on Mac). The formatted SQL appears in the output panel with proper structure and readability.
Copy or re-format — Click "Copy SQL" to copy the formatted result. Use "Swap" to move the output back to input for re-formatting with different options. Click "Clear" to reset both panels.
Review stats — The stats bar shows the keyword count and line count of the formatted output, helping you understand the complexity of your query.

Understanding SQL Formatting

Why Format SQL?

Formatted SQL is easier to read, debug, and maintain. In production environments, queries are often minified or generated by ORMs, making them hard to understand. A formatter adds structure that reveals the query's logic at a glance.

Indentation Levels

The formatter uses indentation to show the hierarchy of a SQL query. Main clauses (SELECT, FROM, WHERE) are at the base level. Conditions under WHERE are indented one level deeper. Subqueries would be indented further, creating a visual hierarchy that matches the logical structure.

Keyword Casing Conventions

Most SQL style guides recommend uppercase for keywords (SELECT, FROM, WHERE) and lowercase for identifiers (table names, column names). The uppercase toggle enforces this convention automatically, ensuring consistency across your codebase.

SQL Dialect Compatibility

The formatter handles standard SQL that works across MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Dialect-specific functions and syntax are preserved as-is since they are treated as identifiers by the parser.

Common Use Cases

Debugging ORM Queries

ORMs like Prisma, Sequelize, or Hibernate often generate long, unformatted SQL. Paste the logged query into the formatter to understand what your ORM is actually executing.

Code Review

Format SQL before submitting pull requests so reviewers can easily understand your queries. Consistently formatted SQL is a sign of professional code quality.

Documentation

Add formatted SQL to technical documentation, wiki pages, or README files. Formatted queries are much easier for team members to read and understand.

Learning SQL

If you are learning SQL, paste examples from tutorials or Stack Overflow into the formatter to see the proper structure with clear indentation and keyword placement.

Legacy Code Cleanup

When inheriting a project with messy SQL queries, use the formatter to clean them up before refactoring. This makes the queries easier to understand and modify.

Query Optimization

A well-formatted query makes it easier to spot optimization opportunities like missing indexes, unnecessary subqueries, or inefficient JOIN patterns.

SQL Formatting Tips

Use Ctrl+Enter (or Cmd+Enter on Mac) as a keyboard shortcut to format SQL quickly without reaching for the mouse.
After formatting, use the Swap button to re-format with different indentation settings. This is faster than re-pasting the query.
Enable the uppercase keywords toggle to enforce a consistent SQL style across your team. Most style guides recommend uppercase keywords.
The formatter preserves comments, so you can add documentation to your SQL before or after formatting without losing it.
For very complex queries with subqueries, format incrementally — format the outer query first, then swap and format subqueries separately.
After formatting SQL, use JSON Formatter to format JSON data alongside your queries for consistent code documentation.
