Common Lisp Library for working with Microsoft Excel XLSX files, for example for ETL (extract-transform-load) and data cleansing purposes. This library is geared for working with large files (i.e. 100MB excel files).
It does not load the whole file into RAM, thus, processing large files is possible. However, be careful with files that contain a lot of "unique strings" (strings that do not repeat frequently on the file), for they need to be loaded onto RAM.
The software is still work in progress, although it works.
