File extension xla is mainly associated with Microsoft Excel, one of the most popular and powerful tool you can use to create format spreadsheets, graphs and much more.
A typical .xla file contains Microsoft Excel add-in files, files that can be loaded in the program as it starts. They contain code (VBA in the case of an xla Add-In) that adds additional functionality to Excel, usually in the form of new functions or tools to execute macros.
Microsoft Excel add-in files sometimes also can have the xll.
MIME types:
application/excel
application/vnd.ms-excel
application/x-excel
application/x-msexcel
You can import the .xla files into Microsoft Excel to install the add-in.
There doesn't seem to exist any option to convert .xla files to anything else. However they are based on VBA code so perhaps some sort of export option may be possible.

Xlib is a client library for the X Window System protocol, written in the C programming language. It provides functions that allow programs to communicate with an X server without requiring the programmer to handle the protocol details directly.
The .xla file contains the archived library components used when building applications with C++Builder. It is a development file rather than a document or a standalone application, and it is not normally opened independently.
The .xla file is intended for use by C++Builder on Microsoft Windows as a library resource for software development. It is not meant to be opened manually by the user.
This is a compiled library archive and is not a document conversion format. It should be used by C++Builder rather than converted.
If the library must be changed, rebuild it from its original source files for the required development environment.
