Which SQL dialects are supported by this formatter?

The formatter supports ANSI SQL, PostgreSQL, MySQL, MariaDB, SQLite, Microsoft SQL Server (T-SQL), Oracle SQL, and Snowflake query syntax.

Does this tool execute or validate my SQL query against a database?

No. This tool operates as a pure lexical formatter and indentation beautifier. It does not connect to any database or execute queries.

The problem: Application logs and ORMs output messy single-line SQL queries that are difficult to read, debug, or review.

SQL Formatter, Beautifier & Minifier: the complete guide

A SQL Formatter, Query Beautifier, and Minifier cleans messy, unindented database statements into standardized, readable SQL with consistent keyword casing and clause indentation. Developers and database administrators frequently copy single-line or obfuscated SQL queries from application logs, ORMs (such as Prisma, Hibernate, and ActiveRecord), or legacy stored procedures. This client-side tool formats SELECT, INSERT, UPDATE, and DELETE queries across PostgreSQL, MySQL, SQLite, and SQL Server without sending proprietary database schemas to external servers.

Standardized SQL Formatting Conventions

Professional SQL style guides (such as the Simon Holywell and GitLab SQL style guides) mandate that major SQL clauses (SELECT, FROM, WHERE, GROUP BY, ORDER BY, HAVING) begin on new lines and keywords appear in uppercase. Nested expressions, subqueries, and comma-separated column projections should indent consistently by 2 or 4 spaces to enhance code review readability.

Minification vs. Beautification for Production Queries

While formatted multi-line SQL is essential for human readability during debugging and code reviews, minified single-line SQL is ideal for production configuration files, environment variables, or embedding inside application string constants where whitespace overhead and newlines can complicate logging pipelines.

Step by step: how to use SQL Formatter

1
Paste your raw, minified, or unformatted SQL query into the left input pane.
2
Select your preferred indentation width (2 spaces or 4 spaces).
3
Toggle UPPERCASE keywords according to your organization's database convention.
4
Click 'Minify SQL' if you need a single-line query for application configuration files.
5
Click 'Copy SQL' to copy the formatted database query directly to your clipboard.

Security & privacy

Database schema and query confidentiality are 100% protected. All lexical parsing, keyword replacement, and whitespace formatting run in local browser memory. No table names, column structures, or database credentials ever touch remote networks.
