What is an SQL Formatter?

An SQL Formatter (also known as an SQL Beautifier) is a tool that transforms raw or minified SQL queries into clean, readable, and structured code. It improves the readability of complex SQL statements by adding line breaks, indentation, casing, and formatting logic.

Why Format SQL?

• Make long SQL queries easier to understand and maintain.
• Improve code review and collaboration in database projects.
• Standardize formatting across your team or organization.
• Detect logical grouping within SELECT, WHERE, JOIN, and CASE blocks.

Fully Customizable Formatting

This tool gives you full control over how your SQL is formatted:

• SELECT break: Choose after how many columns to insert line breaks.
• WHERE break: Set how many conditions appear per line.
• JOIN split: Split each JOIN clause to a new line for clarity.
• CASE split: Format WHEN/THEN blocks on separate lines.
• Letter case: Force keywords to UPPERCASE or lowercase.
• Line prefix/suffix: Add custom text like sb.append(...) at line start or end.
• Comment style: Choose between inline (--) or block (/* */) comments.
• Output mode: View formatted SQL as raw text, code block, or line-numbered list.
• Minify SQL: Compact query into a single line for performance or compression.

Use Cases

• Refactor and document legacy SQL code.
• Prepare SQL for embedding in applications or strings.
• Beautify queries before sharing in presentations or documentation.
• Make SQL queries more readable in debugging and analysis tools.
