# AXL

Introduced in A-Shell 6.3, AXL provides a fully-featured application interface for reading and writing Excel spreadsheet (XLS) files. It is packaged as a collection of ASB functions and procedures built around a third-party library called LibXL. Although the individual functions are all relatively straightforward and intuitive,  there are quite a few of them—over 125. Rather than redundantly documenting all of them here, therefore, the following notes focus on providing an overview, tutorial, index, examples, etc., and rely on [API source code (libxl.bsi)](https://bitbucket.org/microsabio/exlib/src/master/908068/libxl.bsi) for the function-level documentation.
