About this app

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.

In attempting to test the app to see if I would be able to edit and add a theme to my ds flashcart, it refused to save my text changes in any capacity which was the whole reason I downloaded the app.

Sorry, that should not happen. Saving text edits is core functionality, so we’d like to investigate this case. Please contact us at jsongenie@tuyware.com (response on comment is very limited in length) with the file type/source and what happened when saving, so we can reproduce and fix it. Thank you!

It's hard for me to imagine more annoying ads in a JSON editor app. Every time I was about to edit something an ad popped up and ruined my flow.

Sorry for the bad experience. Ads should never feel like they interrupt every edit. We have noticed that we had a bug and we’ve adjusted the timing of full-screen ads so they’re spaced out better during active use. The next release will have this fix. Json Genie Premium is also available if you prefer the app without ads.

Sorry, that should not happen. Saving should continue after a full-screen ad is closed. We’re currently reviewing the ad flow since we saw it had a bug. We cannot reproduce what you describe though, can you contact us at jsongenie@tuyware.com so we can look into this? Thank you.
