Formula 'DAYS' in Excel tables gets replaced with a NamedRange

Hi,

I found out a very strange behaviour when copying a worksheet containing a Table with slightly complex formula on its columns.
Basically I need to copy a worksheet several times in order to be filled with different data sets and remove the original sheet after copy.
In my case the original sheet contains an Excel table with formulae in its columns (see the attached file).
Moreover my Excel file contains also some NamedRanges (in the example there is a named range called ‘Another’).
By running the code below a strange thing happens:
the formula contained in column D2
=IF(IF(ISBLANK([@[Current Projected End Date]]);0;DAYS([@[Current Projected End Date]];[@[Original Projected End Date]]))<0;0;IF(ISBLANK([@[Current Projected End Date]]);0;DAYS([@[Current Projected End Date]];[@[Original Projected End Date]]))))
becomes:
=IF(IF(ISBLANK([@[Current Projected End Date]]);0;Another([@[Current Projected End Date]];[@[Original Projected End Date]]))<0;0;IF(ISBLANK([@[Current Projected End Date]]);0;Another([@[Current Projected End Date]];[@[Original Projected End Date]])))

Basically the same formula except for the fact that DAYS has been replaced with the name of the first named range ‘Another’, thus resulting in a Excel formula error.

The code:
Workbook wb = new Workbook(“Test.xlsx”);
var sourceWorksheet = wb.Worksheets[0];
Worksheet newWorksheet = wb.Worksheets.Add(“NewCopySheet”);
newWorksheet.MoveTo(sourceWorksheet.Index + 1);
newWorksheet.Copy(sourceWorksheet);
wb.Worksheets.RemoveAt(sourceWorksheet.Name);
wb.Save(“output.xlsx”);



Hi,


Thanks for the template file, sample code and details.

After an initial test, I am able to reproduce the issue as you mentioned by using your sample code with your template file. I found that the formula/function ‘DAYS’ in Excel tables gets replaced with a NamedRange. By running the following sample code, the formula contained in the cell D2, i.e.,
"=IF(IF(ISBLANK([@[Current Projected End Date]]);0;DAYS([@[Current Projected End Date]];[@[Original Projected End Date]]))<0;0;IF(ISBLANK([@[Current Projected End Date]]);0;DAYS([@[Current Projected End Date]];[@[Original Projected End Date]]))))"
becomes:
“=IF(IF(ISBLANK([@[Current Projected End Date]]);0;Another([@[Current Projected End Date]];[@[Original Projected End Date]]))<0;0;IF(ISBLANK([@[Current Projected End Date]]);0;Another([@[Current Projected End Date]];[@[Original Projected End Date]])))”
e.g
Sample code:

Workbook wb = new Workbook(“Test.xlsx”);
var sourceWorksheet = wb.Worksheets[0];

Worksheet newWorksheet = wb.Worksheets.Add(“NewCopySheet”);
newWorksheet.MoveTo(sourceWorksheet.Index + 1);
newWorksheet.Copy(sourceWorksheet);
wb.Worksheets.RemoveAt(sourceWorksheet.Name);
wb.Save(“output.xlsx”);
