CSV Viewer
Open and explore CSV files right in your browser
Open, view, edit and download CSV files online for free. 100% private (local processing), no signup, no upload. Works with Excel files too.
I'm Jean, a fullstack dev from France. This is my first launch here, so bear with me.
The backstory is pretty boring, honestly. At work, people kept sending me CSV exports. Every single time, I had to wait for Excel to open, watch it butcher my dates, turn phone numbers into scientific notation... just to check what was inside the file.
One evening I thought "this is stupid, I just want to LOOK at the thing" and started building csv-viewer.online on my free time.
What it does:
• Drag & drop a CSV, it shows up instantly
• Sort, search, filter
• No account, no install, free
What it doesn't do: it's not trying to replace Excel or Google Sheets. It's the tool you use in the 30 seconds before deciding if a file is even worth opening in a real spreadsheet.
I've been improving it slowly for a few months based on my own usage and some feedback from colleagues. Now I'd love to hear from people outside my bubble.
Be brutal, I can take it. What's missing? What's annoying? What would make you actually bookmark it?
Thanks for checking it out 🙏
