Hey Product Hunt! 👋 I'm the maker of Excellent JSON. I built this because I was tired of writing Python scripts every time I needed to convert a spreadsheet to JSON with nested structures. The existing tools either: - Don't support nesting - Require coding - Upload your data to a server So I made a visual drag & drop builder that runs 100% in your browser. A few things I'm proud of: • You can create infinitely nested structures • Rename fields without touching the source • Export as array or keyed object • Your data never leaves your computer Would love to hear your feedback! What features would make this more useful for you? 🔗 https://excellent-json.online
