I built a tool called Data.olllo that helps split huge CSV files—like multi-GB datasets—into smaller parts by size, row count, or column value. It’s 100% offline, runs on your desktop, and doesn’t require any coding.

We just published a detailed article explaining how it works: https://olllo.top/articles/article-24-Split-Huge-CSVs-in-Sec...

Would love feedback from folks who deal with messy or oversized data. What features would you want in a CSV splitter?
