Frequently Asked Questions.

Everything you need to know about using this JSON tool safely and efficiently.

What is the best JSON viewer?
The best JSON viewer provides fast parsing, 100% client-side privacy, an interactive expandable tree view, deep node inspection, syntax validation, JSONPath querying, and format converters. realjsonviewer offers all of these features directly in your browser with zero installation, zero server uploads, and no signups required.
How do I view a JSON file?
You can view a JSON file by dragging and dropping it into our online JSON Viewer or clicking the 'Upload' button to select a file from your device. The viewer parses the file locally in your browser and displays its contents in an organized, collapsible interactive tree with type-aware syntax highlighting.
What is a JSON viewer used for?
A JSON viewer is used to visualize, explore, format, search, and debug complex JavaScript Object Notation (JSON) data structures. It simplifies reading large API responses, analyzing nested objects and arrays, finding errors, and copying property paths.
How do I convert a JSON file to a readable format?
To convert compact or minified JSON into readable formatting, paste it into the editor and click 'Format' (or press Cmd/Ctrl + Enter). This pretty-prints the JSON with structured indentation (2-space, 4-space, or tabs), proper line breaks, and optional alphabetical key sorting.
Can I open JSON with Notepad?
Yes, Notepad and standard text editors can open JSON files because JSON is stored as plain text. However, Notepad does not provide syntax highlighting, collapsible trees, validation error highlighting, or path navigation. An online JSON viewer makes reading and debugging JSON far easier.
How to view JSON on mobile or Android?
You can view JSON on any mobile device (iOS, Android, tablets) by opening realjsonviewer in Chrome, Safari, or Firefox. The responsive interface adapts seamlessly to touch screens, letting you paste payloads, expand/collapse tree nodes, format code, and copy values on the go.
How to get data from a JSON file using JSONPath?
You can extract specific properties and arrays using our built-in JSONPath Tester. Write queries like '$.users[*].email' or '$..price' to filter and extract matching items with real-time evaluation and 1-click result copying.
Can a JSON file be opened in Excel or converted to CSV?
Yes. Switch to the 'Table' tab to preview arrays of JSON objects in a clean spreadsheet grid, then click 'Export CSV' to download a file that opens immediately in Microsoft Excel, Google Sheets, or Apple Numbers.
What can I convert a JSON file to online?
You can convert JSON files into multiple formats with one click, including TypeScript interfaces & types, CSV spreadsheets, YAML configurations, XML documents, and Python dictionaries.
How do I open or print a JSON file to PDF?
After formatting your JSON in the Raw or Tree view, use your browser's Print dialog (Cmd/Ctrl + P) and select 'Save as PDF' to generate a clean, syntax-highlighted PDF document of your formatted data.
How do I copy the exact JSONPath of a property?
Simply click or right-click any key or value in the Tree View and select 'Copy JSON Path' to copy paths like $.users[0].profile.email.
Does the JSON Viewer support large files?
Yes. Our tree renderer uses lazy DOM expansion, only rendering child nodes when you expand a branch. This keeps the page fast and responsive even for large JSON datasets.
