YourDataKit Keeps the Spreadsheet in the Browser

Field notes

The interface organizes spreadsheet operations into Clean, Transform, Analyze, Files, and Export groups, including duplicate removal, calculated columns, pivot tables, file comparison, and combining files. It accepts CSV and both XLSX and XLS formats, then offers CSV, Excel, and JSON downloads. The page also exposes practical machine-learning-adjacent actions such as train/test splitting, random sampling, shuffling, one-hot encoding, and scaling. Its privacy claim is explicit: processing stays in the browser rather than being sent to a server.
