JSON Viewer & Validator

JSON Viewer opens .json files on your phone the way a code editor would: folded into a tree you can open level by level, with keys, text, numbers and true or false each in their own color.

Built for the moments when a JSON file lands on your phone and nothing opens it: an API response, an app export, a config file, GeoJSON, a log in JSON Lines.

READ IT
• Tree view: tap to open or close any object or array, see how many keys or items each holds
• Text view: pretty printed with line numbers and colors, 2 or 4 space indent
• Tap any value to see its full path, like $.orders[2].customer.city, and copy the path or the value
• Expand all or collapse all in one tap
• File info: objects, arrays, keys, values and how deep it goes

FIX IT
• Broken JSON is not a dead end. You get the exact line and column, the line itself with the mistake marked, and the lines around it
• Common slips are named: a comma after the last item, a missing comma, single quotes, keys without quotes

FIND IT
• Search keys and values together. The tree opens itself to every match and you step through them one by one

SAVE IT
• Save formatted, minified, or with every key sorted alphabetically
• Copy the formatted text or share the file
• Paste JSON straight from the clipboard

PRO
One payment turns a list of records into a CSV table for Excel or Google Sheets, nested fields included, and removes ads. Everything else is free, with no limit on file size or count.

Your files are read on your phone and never uploaded.
