RowSwift

Major update: Save datasets to your library and access them across all your devices with iCloud sync.

RowSwift lets you explore and analyse comma-separated files right on your device. Open a CSV from Files, iCloud Drive, a URL, or the clipboard and inspect its structure.

The app summarises each column by showing counts, unique values, minimum and maximum, mean, and quartiles. You can switch between histogram, box-plot, scatter-plot, pie chart, and line views to understand distributions and relationships. When a file is large, row filters help you focus on the portion that matters while keeping scrolling smooth. Any chart can be saved as a PNG, and data can be written back to CSV.

All processing stays on your device. RowSwift collects no analytics and requires no account.
