I have a process that generates a daily file that is being recognized as a MS Excel 97-2003 worksheet file on my computer.

I am able to open the excel file and interact with the data in the file without any issues outside of Alteryx.
When I use Input Data tool to input the excel file, I see the following error.

I have suspicions that the MS 97-2003 file is not actually an excel file given that when I try to save the excel file, I see the following message.

If I save the excel file by changing the format to .xlsx for example, Alteryx has no issue reading the file. However, this adds a manual step to the process, which I am trying to avoid.
Any suggestions on how to read the source file as is, or if I can somehow transform the file using Alteryx to get to the underlying data?
