Im having some issues creating a flow to read excel data. For some reason, Flow / OneDrive is saying that the workbook file format doesnt match the extension.
I have a single tab excel file, the flow triggers when an email is received, it saves the file to Onedrive, then uses Excel Online (Business) to get rows in the table. I triggered the flow from an email I sent in and it worked fine in 15 seconds, but then after editing the flow and re-running it using the same trigger the flow runs for 10 minutes and times out saying
"This workbook couldn't be opened because the file format may not be matching with the file extension"
This makes no sense as sometimes it accepts the file and other times it gives this error.
It is a normal .xlsx file. I rebuilt the file and tried again, same issue. I've not had this kind of inconsistent issue before with Power Automate. What is causing this?
