Clear Cell range values and preserve formulas


I am using Cells.ClearContents(Int32, Int32, Int32, Int32) to clean up a range of cells.
The method works fine, however, I noticed that it deletes the formulas as well.
Is there a method that clears a cell range while also preserving the formulas?

Alternatively, is there a method that checks if a given cell contains a formula?
I’m thinking of changing the way I clear the content. I could iterate over each cell and clear it if it doesn’t contain a formula.

You may use Cell.IsFormula property to check if cell contains a formula or not. Give a try to the following sample code and share the feedback.

Workbook wb = new Workbook("book1.xlsx");
for(int i = 0; i < 20; i++)
    Cell cell = wb.Worksheets[0].Cells[i, 1];
    if (!cell.IsFormula)
        cell.Value = "";

I tried your code, it’s working.
