## What is Calven?

Calven – Response Parser is a private JSON workbench for iPhone and iPad that helps you validate, format, inspect, and compare structured data. Paste a JSON payload and Calven checks it continuously as you type, showing clear error messages with the exact line and column when something is wrong. Pretty-print documents with consistent indentation or minify them into a compact single line while preserving the original key order. Explore complex responses as a collapsible tree with value types and child counts for easier navigation through nested objects and arrays. Compare two saved documents structurally to see which keys were added, removed, or changed, together with their full paths. Review useful document statistics including file size, nesting depth, key count, and totals for objects, arrays, strings, numbers, booleans, and null values. Save frequently used documents and reopen them from history whenever you need them. Built-in examples help you explore common JSON structures and see how parsing errors are reported. Calven works entirely on your device with no network requests, account, analytics, or tracking. Whatever you paste remains on your device, making it suitable for sensitive API responses, configuration files, and tokens.
