Description from store
A tool to help you convert JSON data to CSV format.
Automatically spots JSON pages - When you visit a page that's mostly JSON data, a convert button appears in the corner
One-click conversion - Click the button and get an instant CSV download, no copy-pasting required
Handles messy JSON - Flattens nested objects, converts arrays, deals with mixed data types automatically
Manual backup option - Paste any JSON into the popup if auto-detection misses something
Works locally - All processing happens in your browser, your data doesn't go anywhere else
Smart about when to show up - Only appears on pages where JSON is actually the main content, not on random websites
No setup needed - Just the extension and it's ready to go.
Let me know if you find any bugs or need any additional features and I will be happy to look into it.
Feel free to send any feedback good or bad or any ideas you'd like to see created as I am always looking for a new project to start.
============================================================
1.1.0 Update
Version 1.1.0 transforms the JSON to CSV Converter from a simple conversion tool into a comprehensive JSON processing suite. Users can now:
1. **Prettify JSON** with coloured syntax highlighting
2. **Explore JSON structures** with collapsible tree navigation
3. **Copy clean JSON** without UI artifacts
4. **Convert to CSV** from both raw and prettified views
=============================================================
1.1.1 Bug Fixes
Fixed: CSV Button Not Working in Prettified View
Issue: After prettifying JSON, the "Convert to CSV" button would fail to work properly
Fixed: Single Objects Incorrectly Converted to Key-Value Pairs
Issue: Single JSON objects were always converted to "Key,Value" format instead of recognizing when they should be treated as data records with columns
