Why Use an SQL Formatter?
Structured Query Language (SQL) is the backbone of data interaction. However, when writing complex queries—especially those auto-generated by ORMs or copied from obscure logs—the syntax often becomes a single, unintelligible block of text.
An SQL Formatter (or "beautifier") parses that raw text and injects proper whitespace, indentation, and capitalization. This makes the code readable for humans, which is critical for debugging logic errors or reviewing pull requests.
Multiple Dialect Support
Not all SQL is created equal. Different database management systems (DBMS) have their own specific keywords and grammatical quirks. This tool supports:
- Standard SQL: The baseline ISO standard.
- PostgreSQL: Accommodates Postgres-specific data types and operators.
- MySQL / MariaDB: Handles backtick quoting and specific string concatenations.
- T-SQL: Microsoft SQL Server's proprietary extension.
- SQLite: The ubiquitous lightweight database engine.
Local Formatting for True Data Privacy
SQL queries often contain highly sensitive business logic, table schemas, or even hardcoded PII. Submitting your query to a random online formatter means your database structure is being saved on their servers.
We designed this tool differently. The entire parsing and formatting engine is downloaded to your browser when you load the page. Your SQL queries never leave your computer. Period.
Customization Options
We know every engineering team has different styling standards. Use the configuration bar above to tweak the output:
- Indentation: Choose between 2, 4, or 8 spaces to match your IDE defaults.
- Keyword Capitalization: Automatically force SQL keywords (SELECT, FROM, WHERE) to be uppercase, lowercase, or preserve their original state.
- Logical Operators: Choose whether AND / OR statements break before or after the operator.
