Hey Product Hunt! I’m the maker of CSVViewer. I built it to make everyday CSV tasks simpler: open a file, check the data, make a few edits, and export what you need. The focus is privacy and convenience. Your files are processed locally in your browser, with no server uploads or signup required. You can: * View and edit CSV files * Search, sort, and choose columns * Export CSV or Excel * Convert between CSV and JSON, Excel, Markdown, or TXT One example is the [JSON to CSV converter](https://csvviewer.org/json-to-csv/), which flattens nested objects and lets you preview the table before downloading. It’s free to use. I’d love feedback from developers and anyone who works with data exports: what task or conversion should I focus on next? Thanks for trying it!
