Store listing
By CosmoVex, from Google Play“Open, read, format and fix JSON. Export to Excel, CSV or PDF. Works offline.”
Description by CosmoVex Written by the developer, not by AppBrain. Click to read.
No sign-in. No upload. The file stays on your phone, and everything works offline.
OPEN ANY JSON
• Tap a .json file anywhere on your device and it opens here
• Paste from the clipboard — JSON is detected for you
• Load straight from a URL, or open a .har network capture
• Minified and multi-megabyte files open without a blank screen
READ IT CLEARLY
• Tree view — expand and collapse, so a large file makes sense at a glance
• Formatted view with colour-coded syntax and line numbers
• Table and grid views for arrays of records
• Search across keys, values and text
• Breadcrumbs show exactly where you are in a deep structure
• Adjustable font size, dark and light themes
REPAIR BROKEN JSON
• Fixes trailing commas, single quotes, unquoted keys and missing brackets
• Lists exactly which repairs were made, so nothing changes silently
• Validation points at the line and column that failed
FORMAT AND EDIT
• Prettify or minify in one tap
• Edit in place with validation as you type
• Add, rename, duplicate and delete nodes
• Sort keys alphabetically
• Jump to any line
CONVERT AND EXPORT
• Excel, CSV, PDF, XML, YAML and Markdown
• Copy as CSV, XML, key-value pairs or Base64
• Save to your device or share anywhere
ALSO INSIDE
• JSONPath queries
• Compare two JSON documents side by side
• Templates to start from
• Favourites and recent files
• A built-in API client for quick requests
WHO IT IS FOR
Developers checking an API response on the move. QA engineers reading a payload
from a bug report. Anyone handed a .json file with no idea what is inside it.
PRIVACY
Files are processed entirely on your device. Nothing is uploaded, and no account
is required.
Recent changes:
• Fixed freezes when opening minified JSON — a file on a single long line no
longer stalls the editor. Large and minified files now open smoothly.
• The editor tells you when a file is minified instead of calling it "too
large", and offers one-tap Prettify to make it editable.
• Reworked the rating prompt so feedback reaches us instead of getting lost.
• Stability improvements.
