SQL Indentation Formatter for Developers

About This Tool

This SQL Indentation Formatter for Developers is designed for software developers who work with SQL data daily across APIs, configuration files, databases, and application code. It provides a professional-grade processing environment with developer-friendly features: proper syntax validation, detailed error messages for invalid input, and optimized output formatting that follows industry conventions. The tool runs entirely client-side using JavaScript, meaning your sensitive API responses, configuration secrets, and proprietary data structures never leave your machine. This is particularly valuable in enterprise environments where data privacy policies prohibit pasting sensitive information into cloud-based tools. The zero-installation, zero-configuration approach means you can use it instantly during debugging sessions, code reviews, and development without interrupting your workflow.

What is SQL Indentation Formatter?

A SQL indentation formatter adjusts the indentation of SQL queries without changing keyword casing or query logic. It offers three modes: 2-space indentation (compact, good for screen space), 4-space indentation (traditional, more visual separation), and flatten (single line, useful for logging and configuration). The tool preserves all SQL keywords, identifiers, and values while only modifying whitespace and line breaks. This is useful when you need to convert SQL between different indentation standards, prepare queries for specific contexts (logs require single-line, documentation requires multi-line), or standardize indentation across a codebase.

How to Use This Tool

1. Paste your SQL.
2. Click Indent (2 spaces), Indent (4 spaces), or Flatten.
3. Copy the reformatted result.
