JSON View

Features
Read full description

JSON View is a clean JSON viewer and editor. Open, view, edit, format, and validate JSON files โ€” all offline, no account required, no ads. Whether you're a developer debugging an API response, a data analyst inspecting config files, a student learning JSON syntax, or someone who just received a .json file and needs to read it โ€” JSON View handles it efficiently. TREE VIEW โ€” EXPLORE JSON VISUALLY Navigate complex, deeply nested JSON with a collapsible tree view. Each node shows the key name, value type, and child count at a glance. Tap to expand or collapse any object or array. Color-coded types make it easy to spot strings, numbers, booleans, and null values without reading every line. Auto-expands the first two levels when you open a file โ€” so you see structure immediately, not a wall of collapsed nodes. TEXT VIEW โ€” READ & EDIT WITH SYNTAX HIGHLIGHTING Switch to a full syntax-highlighted text view with line numbers. Every key, string, number, boolean, and bracket is color-coded for quick scanning. Edit your JSON directly in the text editor โ€” fix typos, update values, restructure data. JSON View gives you both a visual tree view AND a real text editing mode with syntax highlighting, giving you the flexibility to work exactly how you want. FORMAT & BEAUTIFY Beautify messy, minified JSON into a clean, readable structure with one tap. Choose your indentation โ€” 2 spaces, 4 spaces, or tabs. Minify bloated JSON into compact single-line output for APIs or configs. Sort keys alphabetically to organize your data. VALIDATE BEFORE YOU SAVE Real-time JSON validation catches syntax errors before you save. See exactly which line and column has the problem โ€” no more guessing. JSON View validates your file every time you save, so you never accidentally corrupt a file. Auto-fix common mistakes like trailing commas, missing quotes, and extra brackets. OPEN JSON FROM ANYWHERE Pick a .json file from your device storage using the built-in file browser. Paste JSON directly from your clipboard โ€” no file needed. Load JSON from any URL (paste an API endpoint and see the response). Receive JSON shared from other apps. Start from scratch with a blank file or use starter templates (API Mock, package.json, Config Map). JSON View works with the Files app โ€” tap any JSON file and open it directly in JSON View. SAVE, SHARE & EXPORT Save changes back to the original file. Save as a new .json file anywhere on your device. Export to XML or PDF for sharing with non-technical colleagues. Share formatted JSON as text to any messaging or note-taking app. Copy the entire file to your clipboard with one tap. CONVERT BETWEEN FORMATS Convert JSON to XML and XML to JSON with a single tap. Useful when you need to switch between data formats for different systems, APIs, or team members. Transform key casing โ€” convert between camelCase, snake_case, and PascalCase across all keys in your file. DESIGNED FOR REAL USE Modern, clean interface optimized for your device. Dark mode and light mode with system-aware auto-switching. Works completely offline โ€” no internet connection needed. No account, no sign-up, no login. No data collection โ€” your JSON files never leave your device. Handles deeply nested structures and large files smoothly. Built by Garoono โ€” indie developers who ship useful tools for real people.

About

Diff Checker

Features
Read full description

Compare two versions of any text and see exactly what changed โ€” line by line and word by word, highlighted the instant you paste. Most "spot the difference" attempts end in squinting at two walls of text side by side. DiffCheck does the reading for you: paste an old version and a new one, and every addition turns green, every deletion turns red, so the change jumps out in a second. It works on code, config files, contracts, and plain prose alike โ€” and it never sends a single character off your device. WHAT YOU GET - See every change at a glance โ€” additions in green, deletions in red, nothing missed - Switch between line-level and word-level diffs to catch even a single edited character - Read changes in a clean side-by-side split view that lines the two versions up - Copy a ready-to-use unified patch of any comparison straight to your clipboard - Keep a local history of past comparisons so you can revisit what changed and when - Save reusable snippets and sample diffs to compare the same text again fast PERFECT FOR - Developers reviewing code, pull requests, and config changes on the go - Writers and editors checking edits between two drafts - Legal and business users comparing contract or document revisions - Students learning how diffs and the unified patch format work WHY NOT JUST EYEBALL IT Reading two versions by hand is where mistakes hide โ€” a flipped number, a deleted clause, a changed flag. DiffCheck compares them character by character so you catch the change you would have scrolled right past. PRIVACY Your text never leaves your device. There are no accounts, no servers, and no tracking โ€” every comparison happens fully offline. FULL ACCESS DiffCheck is free to compare text. Full Access unlocks word-level diffs, the side-by-side split view, saved comparison history, and unified patch export. Choose the plan that fits: - Weekly plan - Yearly plan - Lifetime one-time purchase Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period; manage or cancel anytime in your App Store settings. The lifetime option is a one-time purchase.
