Format and beautify SQL queries with syntax highlighting and validation
Format, validate, and optimize SQL queries
SQL formatting is the process of organizing SQL code with proper indentation, line breaks, and consistent keyword casing to improve readability. Well-formatted SQL is easier to debug, maintain, and collaborate on. It helps developers quickly understand query structure, identify issues, and follow best practices for database development.
To format SQL queries, paste your SQL code into the input area and click the 'Format SQL' button. You can customize formatting options including SQL dialect (MySQL, PostgreSQL, SQL Server, Oracle), indentation size, keyword casing, and line break preferences. The tool will instantly format your SQL with proper indentation and spacing.
The SQL formatter supports Standard SQL, MySQL, PostgreSQL, SQL Server, and Oracle SQL dialects. Each dialect has specific keywords and syntax rules. Select your preferred dialect from the dropdown menu to ensure proper formatting according to that database system's conventions.
Yes! Switch to 'Minify' mode to compress SQL queries by removing all unnecessary whitespace, line breaks, and comments. Minified SQL is useful for production environments where file size matters. This reduces the query size while maintaining functionality, making it ideal for embedding in applications or APIs.
The validation mode checks your SQL syntax for common errors such as mismatched parentheses, missing clauses, and empty statements. While it performs basic syntax validation, it's recommended to test queries in your actual database environment for complete validation. The tool will display validation results and highlight any detected issues.
Absolutely! Click the 'Upload SQL' button to upload .sql or .txt files containing SQL queries. The tool will automatically load the file content into the input area. After formatting, you can download the formatted SQL using the 'Download' button, which saves it as a .sql file.
You can customize several formatting options: SQL dialect (Standard, MySQL, PostgreSQL, SQL Server, Oracle), indentation size (2, 4, or 8 spaces), uppercase keywords (ON/OFF), and line breaks after commas. These options allow you to match your team's coding standards or personal preferences for SQL formatting.
Yes! All SQL formatting, minification, and validation is performed entirely in your browser using JavaScript. No SQL queries or data are uploaded to our servers or transmitted anywhere. Your sensitive database queries and data remain completely private and secure on your device.
