CSV files are everywhere. Exports from databases, analytics platforms, CRMs, and financial systems, yet the tools for editing them are either overkill or painfully slow and complex. Excel is too complex for most cases, and also silently corrupts your data. Text editors show raw commas. Web tools want you to upload sensitive files to someone else's server.
Rowly is different. It does one thing and does it exceptionally well: lets you interact with and understand your CSV files with speed, precision, and zero friction.
Fast
Rowly opens in under a second. Large files parse in a background thread so the interface never freezes. Virtual scrolling means a 100-row file and a 100,000-row file feel exactly the same. Your Mac stays responsive no matter what.
Private
No cloud. No account. No telemetry. No network requests. Your files never leave your machine. Rowly reads and writes plain text -- no proprietary formats, no formula evaluation, no silent type coercion. What you see is exactly what gets saved.
Keyboard-First, Mouse-Friendly
Navigate cells with arrow keys. Edit in place with Enter. Open the command palette with Cmd+K. Every action has a keyboard shortcut, but nothing requires memorization -- menus and toolbars are always there too.
