Json Genie: JSON Editor/Viewer

Json Genie is a fast, private JSON viewer, editor, formatter, merger and compare tool for iPhone and iPad.

Open JSON and JSONC files, view them in a clean tree structure, search keys and values, edit data, compare differences, merge files, pretty-print, minify and share the result.

No account. No cloud upload. Your JSON files stay on your device.

Built for practical JSON work on mobile, Json Genie helps you open a file, understand its structure, make changes safely and move on.

View JSON clearly

Turn raw JSON into a readable object and array tree view. Browse nested objects, arrays, strings, numbers, booleans and null values without losing your place.

Open JSON from anywhere

Use Json Genie as a JSON file opener for files on your device, pasted text, shared content, URLs and supported archives. Open .json and JSONC files from Files, Mail, cloud storage apps, copied JSON text or ZIP archives.

Edit JSON without broken syntax

Edit JSON files without manually fixing commas, brackets or quotes. Change strings, numbers, booleans and null values. Add, edit, clone, delete, move and reorder objects, arrays and values while keeping the structure clear.

Compare JSON files

Pick two JSON files or open tabs and see what changed. Inspect differences in objects, arrays and values without copying private data into an online JSON diff tool.

Merge JSON files

Combine JSON files directly on your iPhone or iPad. Review the merge summary, inspect the result, then save or share the merged JSON. Useful for config files, exported data, API responses, backups and test files.

Find what matters fast

Search JSON keys, values and paths across your document. Jump to matching results, inspect the surrounding structure and return without losing your place. Smart filters like id: 3, game.id: 3 or city: "Austin" help you find specific data faster.

Format, minify and export JSON

Use Json Genie as a JSON formatter when you need cleaner output, compact JSON, sorted keys or a readable structure before saving or sharing. Pretty-print JSON, beautify JSON, minify JSON, sort keys, share as text or file, or switch to raw text view when needed.

Private local JSON workflow

Json Genie opens, views, edits, searches, compares, merges and formats JSON directly on your iPhone or iPad. Your files are not uploaded to our servers just to inspect, edit or clean them up.

Fast with small and large JSON files

Json Genie is built for speed and clarity, from small JSON snippets to large, deeply nested documents.
