Launched the MVP of CSV Viewer Online
Today, I am super excited to launch the very first version of CSV Viewer Online!
The idea came up when I needed to view a CSV file containing sensitive financial data. I realized that almost every free online CSV viewer requires uploading files to their servers, which felt like a massive privacy risk. I did not want my private data sitting on some unknown server.
So, I built CSV Viewer Online. It runs entirely on the client side, meaning your CSV files are processed locally in your browser and never uploaded anywhere. Your data remains 100% private.
It is lightweight, fast, and supports searching, editing, sorting, and exporting files to CSV or JSON formats.
Please give it a try and let me know your thoughts! I would love to hear your feedback on how to make it even better.
What stood out to me isn't the client-side processing itself.
It's that the same product can end up being adopted for very different reasons than the one that inspired it.
The tricky part is that early feedback can make multiple interpretations look correct at the same time.
That's what I'd probably spend more time pressure-testing before deciding what "better" means, because different interpretations can pull the product in very different directions.
Spot on. I’m already seeing different users asking for completely opposite features (e.g., handling giant datasets vs. adding visual formatting). Getting pulled in too many directions is definitely my biggest worry right now. How would you suggest I pressure-test these early signals without over-complicating the MVP?
Possibly, but I think the harder issue isn’t how to handle conflicting feedback in the MVP.
It’s what gets locked in unintentionally if those signals are treated as equal.
That tends to shape the product more than the MVP itself.
