Copy Only in Excel on OneDrive

I want to share a "lookup" Excel sheet in OneDrive with staff, which allows staff to only copy the data in the cells but not to edit or delete it, without them having to download a copy of the sheet and then copy the data. I've found a solution to add data validation, but it unfortunately doesn't work on all the cells, even though data validation is turned on for the cell. For example I could delete A6. File also contains hidden sheet. Solutions will be welcomed.
