Ask HN: Data.olllo new version – New demo videos and faster data previews

1 olllo 0 5/28/2025, 9:40:54 AM

Hi HN!

I’m the maker of Data.olllo – a no-code AI-powered tool for exploring and analyzing large datasets, now updated with new features and a smoother UX.

⸻

What’s new: • Live demo videos: See how to open and analyze large files quickly. • Works offline, with full local privacy – no data sent to the cloud. • Supports massive files – Excel, CSV, JSON, Parquet.

⸻

See how it works (https://olllo.top)

I built Data.olllo because I got tired of waiting for Excel or VS Code to open big files, and not everyone on my team codes in Python. Would love feedback, ideas, or criticism!

Thanks!
