Hey Product Hunt — I’m Haimi, a solo maker. I built CSV Viewer Online because I kept running into the same small problem: I would download a CSV export, log file, or dataset, and I didn’t always want to open a full spreadsheet app just to understand what was inside. https://csvvieweronline.com/ CSV Viewer Online is a lightweight browser tool for opening CSV files as clean, readable tables. A few things it supports today: Open CSV and other delimited files in the browser Filter and sort columns Handle common delimiters like commas, tabs, and semicolons Pagination for larger tables Table customization such as headers, gridlines, font size, and dark mode It is not meant to replace Excel or Google Sheets. The goal is simpler: make quick CSV inspection less annoying. I’m still improving the product and would especially love feedback on three things: Is the workflow clear enough for first-time users? What CSV viewing features do you expect by default? Should the product stay focused on viewing, or add more lightweight editing/export tools? Thanks for checking it out — honest feedback is very welcome.
