Hi Product Hunt 👋
I'm Stefan, the solo dev behind Tablecruncher—a fast, minimal CSV editor I originally built to handle all kinds of CSV files that Excel or web apps choke on.
What makes Tablecruncher different?
Opens multi-gigabyte CSVs really fast
Native C++ app (Windows, macOS & Linux)
No telemetry, no nonsense
Fully open-source under GPL v3
JavaScript as its embedded macro language
Why open source now?
Tablecruncher started as a side project, and it always was a side project. To keep it alive as a side project, I realized the best path forward was to open source it. It lets me share the tool with others without dealing with the overhead of licensing, payments, or other commercial hurdles.
Plus, it feels good to give back. If this tool can help someone clean up a messy CSV file, that’s already a win.
Would love your thoughts, feedback, and stars ⭐ on GitHub!
Thanks for checking it out

📬 BTW: I'm also writing a newsletter called The Missing Header, about all the weird problems we run into when handling real-world data (encodings, inconsistent dates, undefined structure…). If you're into that, there's a link on my project's page.
