I am a brand new user building my first workflow. I need to import roughly 50 Excel files so that they can be cleaned and combined, with the goal being to leverage Alteryx to do the cleaning more efficiently than the current manual Excel process. These 50 files are all similar but not identical (hence the need for cleaning), and they come from roughly 15 different sources, with each source providing 1-8 files. Files from 14 of the sources are importing perfectly. Files from the 15th source are crashing Alteryx when I run the Input Data tool. I choose the file path and the tab, hit "ok", and then the program stalls and shuts down within seconds. There is nothing outwardly special about the files from this source - they are all small (<20kb), standard .xlsx, single tab, etc. Any insight as to why this might be happening? The only workaround I've found is to open the files in Excel and paste the values into a fresh workbook, then run the input tool on the new workbook, but this reduces the efficiency of an already inefficient data import process! Thanks.
