What file formats can I upload?

You can upload CSV, TSV (tab-separated), or JSON files. You can also paste data directly from spreadsheets.

Is my data sent to a server?

No. All data processing happens entirely in your browser. Your data never leaves your device.

Sum, Count, Average, Min, Max, Median, Count Distinct, Standard Deviation, and Variance are all available.

Yes. Your data and field configurations are automatically saved to your browser's local storage and restored when you return.

There is no hard limit, but performance is best with datasets under 100,000 rows. The tool handles most typical analyst datasets with ease.
