GS-Calc can be helpful, for example, to:

* process large (e.g. 4GB+) data sets in a spreadsheet;

* load GB/32 million-row files in seconds and use them without any crashes;

* load/edit in-place/split/merge/clean CSV/text files with up to 32 million rows and 1 million columns;

* use your Python functions as UDF formulas that can return to GS-Calc images and entire CSV files;

* use a set of statistical pivot data functions;

* create and display all popular chart types with millions of data points instantly.

Suggestions for improvements are welcome (and often implemented quite quickly).
