Excel crashes with large CSV files — how do you handle big data locally?

Hey everyone 👋

I’ve run into Excel limits too many times — opening a 2GB CSV can freeze your machine or just fail entirely.

I recently built something called CSV GB+ under the Data.olllo project — it opens massive CSV files (even 1000GB) directly.

It doesn’t crash, it’s fast, and some features let you manipulate and summarize millions of rows. It’s not a cloud service or browser tool — just a clean, local app you install and use when Excel starts choking.

I’m curious:

• What tools do you use when Excel gives up?

• Do you prefer pandas/Python, Notepad++, database imports, or something else?

And if you want to try CSV GB+ by Data.olllo, there’s a 7-day pro trial (no card needed). I’d really love your feedback:
