What is an XLA file?

An XLA file is an add-in used by Microsoft Excel, a spreadsheet application included in the Microsoft Office suite. It is used to add additional commands and features to Excel. Some XLA files are developed by Microsoft, while others are created by third-party developers and Excel users.

Users can install additional add-ins by downloading or creating their own XLA files and then manually adding those files to Excel.
