SQL Beautifier 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 Beautifier?

A SQL beautifier formats SQL queries with your choice of keyword casing: uppercase (SELECT, FROM, WHERE) or lowercase (select, from, where). While uppercase keywords are the traditional SQL convention and improve readability by distinguishing keywords from identifiers, some teams prefer lowercase for consistency with their codebase style. The beautifier applies proper indentation, line breaks at clause boundaries, and consistent spacing regardless of the keyword case you choose. This flexibility makes it suitable for any team's SQL coding standards.

How to Use This Tool

1. Paste your SQL.
2. Click Beautify (Uppercase) or Beautify (Lowercase).
3. Copy the formatted result.
