## What is JSON XML Viewer?

Read API responses and configuration files without sending their contents to an external service. Paste JSON or XML, or open a text file, and the app detects and formats the data on your device.

KEY FEATURES
- Format and minify JSON and XML
- Highlight keys, strings, numbers, tags, and symbols
- Switch among Formatted, Raw, Key + Value, and Values-only views
- Copy or share the exact output you need
- Keep malformed data visible where possible
- Open UTF-8, UTF-16, and Shift JIS text files
- Preview the beginning of files larger than 10 MB

Formatting, minifying, and value extraction are processed entirely on your device. Pasted text and opened files are not uploaded.

One-time purchase. No ads. No subscription.
