Who Is SQL Formatter & Beautifier Built For?

Database administrators formatting legacy SQL stored procedures and complex join queries
Backend developers debugging ORM-generated SQL queries from Prisma, Hibernate, and TypeORM
Data analysts organizing multi-CTE analytical queries for Snowflake, BigQuery, and Redshift

Key Benefits & Core Capabilities

Multi-Dialect SQL Formatting

Supports PostgreSQL, MySQL, SQLite, T-SQL (SQL Server), PL/SQL (Oracle), and Google BigQuery.

Keyword Uppercasing

Automatically capitalizes reserved SQL keywords (SELECT, FROM, WHERE, GROUP BY, JOIN) for standardized readability.

Indents Complex Joins & CTEs

Aligns subqueries, Common Table Expressions (WITH clauses), and nested CASE statements beautifully.

100% In-Browser Privacy

Format confidential production database queries without exposing schema or table names to cloud APIs.

How It Works & Technical Architecture

The SQL Formatter employs a dialect-aware SQL lexer that tokenizes queries into keywords, identifiers, literals, operators, and comments.

It builds an indentation hierarchy based on SQL clause boundaries (e.g. SELECT clause, FROM joins, WHERE predicates, ORDER BY expressions) and formats keywords according to your casing preferences (UPPERCASE or lowercase).

All formatting executes locally in browser JavaScript, guaranteeing that proprietary table schemas and queries stay confidential.

Practical Use Cases & Applications

Debugging ORM SQL Queries

Paste unreadable single-line raw SQL generated by Prisma, Sequelize, or Hibernate for instant clarity.

Formatting BigQuery & Snowflake Queries

Organize 200-line analytical SQL scripts with properly indented CTEs and window functions.

Standardizing Code Reviews

Format SQL migration files before submitting pull requests for database schema changes.

Legacy Stored Procedure Refactoring

Beautify messy legacy stored procedures to understand complex business logic.

Frequently Asked Questions

Which SQL dialects are supported?

Softnag supports Standard SQL, PostgreSQL, MySQL, SQLite, Microsoft SQL Server (T-SQL), Oracle (PL/SQL), and Google BigQuery.

Can I automatically convert all SQL keywords to uppercase?

Yes. You can choose to automatically uppercase all SQL keywords (SELECT, JOIN, WHERE, etc.) or preserve existing casing.

Does the formatter support complex subqueries and WITH (CTE) clauses?

Yes. Nested subqueries, Common Table Expressions, CASE statements, and JOIN conditions are indented with structural clarity.

Are my private database queries sent to any server?

No. All SQL formatting executes strictly within your browser client.

Can I format queries containing comments?

Yes. Both single-line (-- or #) and multi-line (/* ... */) comments are preserved in their correct context.

Does this tool execute or run my query?

No. Softnag only parses and beautifies syntax formatting purely in your browser.
