SQL Query Formatter for API Responses

About This Tool

Working with REST APIs, GraphQL endpoints, and webhooks means constantly processing SQL response data. Raw API responses are typically minified — stripped of all whitespace and line breaks to minimize payload size — making them virtually impossible to read without formatting. This tool transforms those compact responses into well-structured, readable output that reveals the data hierarchy and makes it easy to locate specific values. Paste a response from Postman, cURL, browser DevTools Network tab, or any API client, and instantly see the formatted result. The tool validates the response structure during processing, catching malformed responses that might cause subtle bugs in your application. For developers debugging production issues, this immediate visibility into API data structures is invaluable.

What is SQL Query Formatter?

A SQL query formatter formats complex SQL statements and provides statistics about the query including line count and keyword count. These metrics help you assess query complexity — queries with many keywords and joins tend to be more complex and may benefit from refactoring into CTEs or subqueries. The formatter handles multi-table joins, subqueries, aggregate functions, GROUP BY/HAVING clauses, and ORDER BY with proper indentation at each nesting level. The statistics output helps teams identify queries that may need simplification, documentation, or performance optimization.
