SQL Uppercase Keywords 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 Uppercase Keywords?

The SQL uppercase keywords tool converts all SQL reserved words to uppercase while leaving table names, column names, aliases, and string values untouched. Uppercase SQL keywords are the most widely adopted convention in the database community because they create a clear visual distinction between SQL syntax and data identifiers. This tool recognizes over 100 SQL keywords including all DML (SELECT, INSERT, UPDATE, DELETE), DDL (CREATE, ALTER, DROP), and flow control keywords (CASE, WHEN, IF). It processes the text in place without changing indentation or line breaks, making it safe to apply to already-formatted queries.
