About the SQL Formatter
This tool is designed to help developers, database administrators, and anyone working with SQL queries to quickly format their code. Well-formatted SQL is easier to read, debug, and maintain, especially for complex queries involving multiple joins, subqueries, and clauses.
How to Use
Simply paste your SQL query into the 'Input SQL' textarea and click the 'Format SQL' button. The formatted output will appear in the 'Formatted SQL' textarea. The tool applies standard SQL formatting conventions, including indentation, line breaks, and consistent casing for keywords.
Frequently Asked Questions
Is my SQL query sent to a server?
No, your SQL query is processed entirely in your browser using JavaScript. Nothing is sent to our servers, ensuring your data privacy.
What SQL dialects are supported?
The formatter applies general SQL formatting rules that are compatible with most common SQL dialects (e.g., MySQL, PostgreSQL, SQL Server, Oracle). While it aims for broad compatibility, very specific dialect-dependent syntax might not be perfectly formatted.
Can I customize the formatting rules?
Currently, the tool uses a predefined set of formatting rules. Future updates may include options for customization.
