Clean unused names?

Hi, is there any function which can clean all ‘unused’ named ranges safely? For example, i would like to clean all named ranges which is not reference in the same workbook?
_workbook.Worksheets.Names.Clear(); … this also clean the name which is refereed to … so not suitable.

@catalparue26,

Thanks for your query.

I think you may check if a named range is referenced or not using Name.IsReferred Boolean attribute, see the sample code segment for your rerference:
e.g
Sample code:

.......
NameCollection names = workbook.Worksheets.Names;
            int i = names.Count - 1;
            while (i >= 0)
            {
                if (!names[i].IsReferred)
                {
                    names.RemoveAt(i);
                   
                } 
              i--;
........

Hope, this helps a bit.
