Json Genie: JSON Viewer/Editor

JSON file opener, viewer & editor with tree view, search, format & JSONC support

Json Genie is a fast JSON file opener, viewer, editor and formatter for Android.

Built by an independent developer and trusted by millions, Json Genie was created for practical JSON work on mobile: open the file, understand the structure, make your changes and move on.

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

Open .json and JSONC files, browse them in a clean JSON tree view, search JSON keys and values, edit JSON data, pretty-print, beautify, minify and share the result.

Your JSON stays local

Json Genie opens, views, edits, searches and formats JSON directly on your device. Your JSON files are not uploaded to our servers just to open, read, edit, pretty-print, minify or inspect them.

That makes Json Genie useful for API responses, configuration files, exported data, logs, backups, app data, test files and JSON content you do not want to paste into an online JSON viewer, JSON formatter or converter.

View JSON clearly

Json Genie turns JSON into a clean object and array tree view that is easier to read on a phone or tablet than raw JSON text.

Browse nested objects, arrays, strings, numbers, booleans and null values in a structured layout without losing track of the data.

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 files from downloads, file managers, email attachments, cloud storage apps, shared files or copied JSON text. You can also set Json Genie as your default JSON handler.

Search and understand JSON

Search through JSON keys, values and paths across your document. Jump to matching results, inspect the surrounding structure and return without losing your place.

Smart filters such as id: 3, game.id: 3 or city: "Austin" help you find specific data faster.

Edit JSON without raw text hassle

Edit JSON files without manually fixing commas, brackets and quotes.

Change strings, numbers, booleans and null values. Add, edit, clone, delete, move and reorder objects, arrays and values while keeping the JSON structure clear.

Format 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, beautify, minify, share as text or file, or switch to raw text view when needed.

Fast with small and large JSON files

Speed has always been one of the main goals of Json Genie. It opens small JSON files quickly and is built to handle large, deeply nested JSON documents without getting in your way.

Built by an independent developer

Json Genie is not a bloated corporate editor. It is built by an independent developer, improved through real user feedback and focused on practical JSON work on Android.
