.xla
is the file extension for pre-Excel 2007 addins written using vba. XLA addins are a special type of workbook that contains vba code or functions integrated into the Excel or VBA environment. This VBA code is meant to add or extend the built-in functionality provided by Excel.
XLA addins are created in Excel's VBA IDE. After inserting code into a VBA module, the workbook is saved in XLA format. This file may then be loaded by Excel to enhance existing or add new functionality which is integrated into the Excel frontend or development environment.
A common use for XLA addins is as a repository for often used VBA functions. The most frequently used user-defined functions (udf) are placed into a separate workbook, which is saved as an Excel addin (.xla
). These functions can then be used as native functions after installing the addin.
