JSON Viewer: Reader & PDF

Open a JSON file. Find the value you need. Share a readable PDF.

JSON Viewer helps you explore data on iPhone and iPad through a clear tree, formatted text and a PDF preview. Read API responses saved as files, configuration files and data exports without editing the original.

EXPLORE THE STRUCTURE
Expand objects and arrays, collapse sections and switch to syntax-colored text. Copy a key, a value or its path when you find what matters.

FIND THE RIGHT VALUE
Search keys and values across the document. Select a result to reveal its place in the tree, with the surrounding structure in view.

TURN JSON INTO A DOCUMENT
Preview and export a formatted PDF with syntax colors, the file name and page numbers. Share or print it, or share the original JSON. Copy the full JSON in formatted or minified form.

KEEP YOUR FILES WITHIN REACH
Open files from Files or another app's share sheet. Keep an archive, rename files and use iCloud Drive when available. Files already downloaded or stored locally can be read offline. No app account is required.

KNOW WHAT IS INSIDE
See file size, value counts and nesting depth. Invalid JSON shows a syntax error with its line and column. Number text and object member order are preserved when formatting.

Open your next JSON file and get straight to the data.
