.XLS file format deprecation and end of life in Alteryx Designer

How To

Address the message: “This file format will be phased out. Go to 24.1 release notes for more information.”

XLS is the Excel Binary File Format Structure, which is the binary file format used by Microsoft Excel 97, Excel 2000, Excel 2002, and Excel 2003. In 2007, Microsoft introduced the .xlsx format with extended capabilities to replace the .xls file format. Microsoft still allows the .xls file format but discourages customers from using it.

Environment

In the coming releases, Alteryx Designer will gradually phase out support for .xls files. Users should start now switching .xls files to a newer format and updating their workflows to avoid errors in the future. See this Microsoft post on how to save .xls files as .xlsx or .xlsm files.

Procedure

As part of this process, Alteryx Designer will also phase out support for the “Microsoft Excel Legacy” file format. Alteryx Designer Tools using this file format should be switched to the “Microsoft Excel” format. This should not require changes to the file itself.

Deprecation Process:

Introduction of a message alerting users that they are using an old file format and should update their files to a newer format.
- The message will read: “This file format will be phased out. Go to 24.1 release notes for more information.”
Removal of .xls as an option from the user interface. New workflows reading from or writing to .xls cannot be created anymore. Existing workflows will continue to run.
End of life: complete removal from Alteryx Designer.
