How large a CSV file can I load?

The practical limit depends on your browser and device memory. Files up to 10 MB (tens of thousands of rows) work smoothly. Larger files may slow down rendering.

Is my data uploaded to a server?

No. Everything runs locally in your browser using JavaScript. Your data never leaves your device.

Can I add or delete columns?

Currently you can add/delete rows. Column operations are available via the CSV Column Extractor tool.

Does sorting modify the data?

Sorting only changes the display order. Download the CSV after sorting to get the sorted file.
