Creator here, happy to answer any questions. The website is based on three great open-source libraries - Perspective, Datalib and DC.js and does a bit of plumbing to reuse the wasm speed of Perspective for dealing with the data. Data does not leave the browser. Supported file size is limited by how much memory allocation browsers allow per tab, that can be overridden if needed but typically up to 1-2gb should work.

It's preliminary work, but if there is interest and is useful to someone I would iterate on it. Drop a line at hello at streamingpivot dot com for questions and requests.

I import a small CSV file and nothing happens - screen stays exactly the same. ? Using Chrome 6.2

Is it happening on each screen - pivot/charts/stats and what does the Chrome Dev console say? You could try to uncheck the "First line is a header" in the settings (cog image on the right) might help if you don't have a header and the first line contains strange symbols. Feel free to drop me a line at hello at streamingpivot dot com, happy to continue the discussion there.

Also tried with several CSV files (2MB and 123kb) and nothing happens. Here is a link to small CSV: https://www.seektable.com/demo/sales.csv

(btw our tool also can create pivot tables/charts by CSV up to 500mb or databases)
