Hi, I am loading in a CSV file and creating a pivot table in a worksheet.
When I write the data back to excel the columns are storing 1's and 0's as type text so when I pivot and SUM them they don't add together as they are of type text. In the excel file I can select Convert to Number and they are good.

How can I get the cells to be set to Number Format through spire. I have Set NumberFormat = "0" but to no avail.

Dear conorpboland,

Thanks for your inquiry.
Please add following code.
Code: Select all
range.IgnoreErrorOptions = IgnoreErrorType.NumberAsText;

If there is any question, please let me know.

Sincerely,

Hi Betsy, No this did not work as the columns still see the 1's adn 0's as text and would not sum them for me.
As a work around I had to loop the sheet and convert which is not ideal

Another question you may be able to help with. Can I dynamically select the end of a range of data if I dont know what the last column is?

I have been trying something with endcell but it is not working. D46 could be any number of rows

// chart.DataRange = sheet2.Range["A2:D46"];
chart.DataRange = sheet2.Range["A2:D2"].EndCell;

CellRange dataRange = sheet.Range["A1:I10000"];
// dataRange.IgnoreErrorOptions = IgnoreErrorType.NumberAsText;

foreach(CellRange r in dataRange)
{
if (r.Cells[0].Value == "1")
{
r.Cells[0].NumberValue = 1;
r.Cells[0].NumberFormat = "0";
}
if (r.Cells[0].Value == "0")
{
r.Cells[0].NumberValue = 0;
r.Cells[0].NumberFormat = "0";
}
}

Dear conorpboland,

Thanks for your feedback.
Sorry that the code didn't work on your side. Yet I confirmed the situation you mentioned could work on my side, maybe there was something different between us caused that issue. Please try to use the latest Spire.XLS Pack Hotfix Version:7.12.76. And below is my entire code and the attachment is my input document.
Code: Select all
            Workbook workbook = new Workbook();
            //load a csv file
            workbook.LoadFromFile(@"F:\sample document\Data.csv", ",", 1, 1);
            Worksheet sheet = workbook.Worksheets[0];
            //get the all range on the sheet
            CellRange range = sheet.Range[sheet.FirstRow, sheet.FirstColumn, sheet.LastRow, sheet.LastColumn];           
            range.IgnoreErrorOptions = IgnoreErrorType.NumberAsText;
            //also need to set the number format
            range.NumberFormat = "0";
            //this formula could work
            sheet.Range["A20"].Formula = "=SUM(B2+B3)";
            //save to excel file
            workbook.SaveToFile("11501.xlsx", ExcelVersion.Version2010);


For your second question, please refer to the code below.
Code: Select all
            CellRange lastCell= range.Cells[range.CellsCount - 1];

Hope it helps.

Sincerely,
Betsy
