SQL Formatter – Format & Beautify SQL Online

How to Use the Online SQL Formatter

Paste or Type Your SQL Query: Enter any unformatted, single-line, or messy SQL query into the left editor panel.
Choose Indentation Style: Select your preferred indentation (2 spaces, 4 spaces, or Tab) from the top toolbar.
Click "Format SQL": The beautifier parses your query, structures major clauses (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY) onto dedicated lines, indents expressions, and capitalizes keywords.
Review the Formatted Output: Inspect the structured query in the right output pane with clear clause hierarchy.
Copy or Download: Click "Copy" to transfer the result directly to your clipboard or "Download" to save formatted.sql.

What Is a SQL Formatter?

A SQL Formatter (also known as a SQL Beautifier or SQL Pretty Printer) is a developer utility that reorganizes raw database query strings into consistent, readable, and standardized layouts. Unformatted SQL queries generated by Object-Relational Mappers (ORMs like Prisma, Hibernate, Entity Framework, or Sequelize) or extracted from application error logs are typically flattened into single, unreadable strings hundreds of characters long.

CodeCrate's SQL Formatter processes your query entirely inside your web browser. It aligns key clauses, separates joins, nests subqueries cleanly, and formats conditions without ever connecting to a database or transmitting proprietary data over the network.

Before & After Example

Unformatted / Single-Line Query

select u.id, u.name, count(o.id) as orders_count, sum(o.amount) as total_spent from users u left join orders o on u.id = o.user_id where u.active = 1 and o.status = 'completed' group by u.id, u.name having sum(o.amount) > 500 order by total_spent desc;

Difficult to scan, spot missing filters, or review during code pull requests.

Formatted & Beautified SQL

SELECT
  u.id,
  u.name,
  count(o.id) AS orders_count,
  sum(o.amount) AS total_spent
FROM
  users u
  LEFT JOIN orders o ON u.id = o.user_id
WHERE
  u.active = 1
  AND o.status = 'completed'
GROUP BY
  u.id,
  u.name
HAVING
  sum(o.amount) > 500
ORDER BY
  total_spent DESC;

Clean, readable, and immediately understandable for any engineer or DBA.

Common Developer Use Cases

ORM Query Debugging

Format dense raw queries extracted from Prisma, Hibernate, TypeORM, SQLAlchemy, or ActiveRecord logs to understand performance bottlenecks.

Pull Request & Code Review

Clean up migration files, database seeds, and complex view definitions before submitting pull requests to ensure consistent team style.

Slow Query Log Analysis

Reformat long, multi-line execution plans captured by MySQL slow query logs, PostgreSQL pg_stat_statements, or AWS RDS Performance Insights.

Documentation & Runbooks

Generate clean, readable SQL snippets for engineering wikis, onboarding guides, schema documentation, and post-incident reviews.

Technical Notes on SQL Formatting & Safety

Formatting vs. Optimization: CodeCrate's SQL Formatter is strictly a lexical formatting utility. It reorganizes whitespace, line breaks, and casing to improve human legibility. It does not analyze execution plans (EXPLAIN), re-order indexes, validate table schema existence, or attempt query performance optimization.

No Database Connection: Unlike administrative database tools, this utility never connects to PostgreSQL, MySQL, SQLite, Oracle, SQL Server, or Snowflake. You can safely format queries containing sensitive WHERE conditions without risking database side effects or network exposure.

Preserving String Literals & Comments: The formatter's tokenizer preserves text within single quotes ('text'), double quotes ("column"), inline comments (-- comment), and multiline block comments (/* ... */) without altering internal whitespace or text casing.

Frequently Asked Questions

Does this SQL formatter execute or test queries against a database?

No. This tool is strictly an in-browser code formatter. It never connects to any database server, never runs queries, and never transmits your SQL commands to any remote machine.

What SQL clauses and statements are supported?

The formatter handles common DQL, DDL, and DML statements including SELECT, INSERT INTO, UPDATE, DELETE FROM, CREATE TABLE, WHERE, JOIN (INNER, LEFT, RIGHT, FULL, CROSS), GROUP BY, ORDER BY, HAVING, and nested subqueries.

Does the tool capitalize SQL keywords automatically?

Yes. Key SQL reserved words are standardized to uppercase (e.g. select becomes SELECT, left join becomes LEFT JOIN) for consistent, readable team coding standards.

Can I format subqueries and nested SELECT statements?

Yes. Nested queries enclosed in parentheses are indented proportionally, keeping subquery conditions organized and readable.

Can I download my formatted query?

Yes. Use the Download button to save the beautified output as a formatted.sql file or copy it straight to your clipboard.

What indentation styles are available?

You can select 2 spaces, 4 spaces, or Tab characters depending on your repository guidelines or database IDE conventions.
