Your data never leaves your device.
Everything runs in your browser. Your projects live on your device.
- Runs entirely in your browser. We don't upload or store your CSV files on our servers.
- Projects are saved locally in your browser. Clearing site data or using Incognito will remove them—export projects to back them up.
- For very large files, split into smaller chunks or use streaming mode; we're building a Desktop app for heavy workflows.

Frequently Asked Questions
Everything you need to know about RowLab and how it can transform your data workflow.
Really large files? The Desktop app is coming.
The browser handles files comfortably up to ~50MB, and can stream up to 200MB. Beyond that, the Desktop app will run the same deterministic pipelines natively — no upload, no tab limits.
- Native performance for files that stall a browser tab — hundreds of MB and beyond.
- Watch a folder and auto-run your pipeline on every new file that lands in it.
- Fully offline. Same deterministic engine, no browser memory ceiling.
