Hi, thanks for the response. The tab is not blank. The Excel file is used for daily import of portfolio data, and this tab contains what was already imported (so we don't dupe data). It has about 3,000 rows. There are two cells to the right of each table row that extract and concatenate table data (and we drag these two cells down to new rows returned by the Export). Since I upgraded to Excel 2016, when I run the Export, stray data is pulled in from another tab on the new rows, to the right of the table data. (There is another Admin who has his own copy of this spreadsheet, and he has the same issue.)
I tried creating a new (blank) tab and running the Query, but could not recreate the issue.
