SQL Formatter

Our SQL Formatter analyzes your raw SQL code and applies industry best practices for readability. It doesn't change the logic of your query; it only adjusts its presentation.

When you paste a block of code, the tool identifies keywords (like SELECT, FROM, WHERE), column names, and operators. It then automatically applies consistent indentation, line breaks, and standard capitalization.

The multi-dialect support allows it to understand syntax variations—whether you are writing PostgreSQL, MySQL, or SQL Server code. For example, it will correctly format a UNION query structure regardless of the specific database engine you target, ensuring clean output every time.

To get the most benefit from our SQL Formatter, structure your input logically before pasting it into the tool.

• Use Comments: If you have complex sections (like a large subquery), wrap them in comments (e.g., /* Start of User Filters */). This helps the formatter maintain context and readability around those blocks.
• Keep Dialects Separate: When dealing with multiple SQL files, process them individually rather than pasting all dialects into one input block to ensure maximum accuracy for each syntax rule.
• Review Output vs. Input: After formatting, quickly scan the output to confirm that line breaks or indentation did not accidentally break an intended string literal or function call structure.
