Hi Dave_Williams,
Sorry that with the
Split Data feature, the data been split would go to a new workbook.
However, you could use the
Combine feature to combine all the sheets from different workbooks into one workbook after you apply the
Split Data feature. To access the feature, please go to the tab
Kutools Plus, in the group
Workbooks & Sheets, find
Combine. Then click
the third option in the pop-up window.
You can follow the dialog boxes, or if you need a tutorial, please click here:
