SQL Formatter for Config Files

About This Tool

Configuration files are at the heart of modern software development — from package.json and tsconfig.json to VS Code settings and cloud infrastructure templates. This SQL Formatter for Config Files is tailored for processing SQL configuration files with the precision and care they require. Configuration files often contain comments (in formats that support them), version-specific settings, and carefully structured hierarchies that must be preserved during formatting. The tool processes these files while maintaining all data integrity, ensuring that indentation reveals the logical structure of configuration sections, nested settings, and conditional values. Whether you are cleaning up auto-generated configuration, merging settings from multiple sources, or preparing config files for documentation, this tool handles the task reliably.

What is SQL Formatter?

A SQL formatter transforms raw, single-line SQL queries into cleanly formatted statements with proper indentation, line breaks at clause boundaries (SELECT, FROM, WHERE, JOIN, etc.), and standardized keyword casing. Well-formatted SQL is dramatically easier to read, debug, and review than single-line queries. The formatter applies industry-standard formatting conventions: major clauses start on new lines, JOIN conditions are indented, AND/OR conditions are clearly separated, and keywords are uppercased for visual distinction from table/column names. This tool supports all standard SQL syntax including SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, subqueries, and Common Table Expressions (CTEs).

1. Paste your SQL query.
