Hello

tWaitForFile component will monitor a specify folder and tigger one thing once you create a new file or delete a file. In your case, if you just want to monitor one folder whether there are some new files created and convert them to an excel sheet, you needn't to use tFileList component. Do it like this:
tWaitForFile --Iterate-->tFileInputDelimited--main-->tUnit--->tFileOutputExcel

Best regards
