Unfortunately, this is not accurate to the contents of the excel files. Each of the other files have eight sheets each, but Refine only brought in the first four.
After a little testing, if I select less sheets, each file only brings in that many sheets (select three in Parsing Options, get three per file), discarding any additional sheets that might be in the workbook. Additionally, if I select four sheets and one of the files doesn't have that many sheets, the import process will hang and not complete.
There are some manual steps to the cleanup that I'm doing in Refine, so it won't be much of an issue to import each of the seventeen spreadsheets in turn. I wanted to bring this to folks' attention to a) report this as a bug or b) have someone point out a solution. I appreciate your feedback!
