epplus

I'm using EPPlus to generate Excel files, in DAL I'm populating DataTable , filling data into table, and passing table to Presentation Layer. From there I'm using LoadFromDataTable() method to generate Excel file. Everything works fine, except that I want to set one of the column's type to Date . I tried to set Column type of my DataTable to Date and than pass DataTable to Presentation Layer, but it seems EPPlus either, ignored it, or didn't recognize, because when I'm opening generated Excel file, cell's type is Number . If I manually Format Cells and set Type to Date , Excel shows correct

The problem: I am using EEPlus. I am stuck at applying a hex color code, e.g. #B7DEE8 , for a cell in my Excel sheet. I got the following (working) code: ws.Cells["A1:B1"].Style.Fill.PatternType = ExcelFillStyle.Solid; ws.Cells["A1:B1"].Style.Fill.BackgroundColor.SetColor(Color.Gray); But I need something like the following: ws.Cells["A1:B1"].Style.Fill.BackgroundColor.SetColor("#B7DEE8"); So my question is: is it possible to use hex color codes with EEPlus? If so, how can I do that? Yograj Gupta Try this Color colFromHex = System.Drawing.ColorTranslator.FromHtml("#B7DEE8"); ws.Cells["A1:B1"]

Hello I have this code where i create an xlsx file and i need to pre set the width of the xlsx sheet cells. The actual problem is that when i open the excell i need to double click on the gap between the columns with the mouse in order to unwrap the columns and revieal the data that is hidden. Is there a way to do this programmaticaly with Epplus? using (ExcelPackage p = new ExcelPackage()) { String filepath = "C://StatsYellowPages.csv"; DataSet ds = ExportCSVFileToDataset(filepath, "tblCustomers", "\t"); //Here setting some document properties p.Workbook.Properties.Title = "StatsYellowPages";

I'm new to epplus , and i'm trying to read some values from an excel table. This is what i have so far: var fileInfo = new FileInfo(filename); using(var excelPackage = new OfficeOpenXml.ExcelPackage(fileInfo)) { foreach (var sheet in excelPackage.Workbook.Worksheets) { foreach (ExcelTable table in sheet.Tables) { foreach(var row in table.Rows) // <-- !! { ... } } } } However, now i'm stumped, as the ExcelTable only has a Columns property, but not a Rows property as i had expected. I cannot find a Rows property on any object in the library. How do I iterate through a table, reading Row for Row?

using code like using OfficeOpenXml; // namespace for the ExcelPackage assembly … FileInfo newFile = new FileInfo(@"C:\mynewfile.xlsx"); using (ExcelPackage xlPackage = new ExcelPackage(newFile)) { … } I get an exception error of 'IBM437' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method. Parameter name: name Any ideas as to what the problem could be? Thanks Martin The problem is in the ZIP file reader ( ZipInputStream ). You need to add the encodings like windows-1252 manually: dotnet add package

I've created an endpoint that generates an Excel file. It's supposed to function as a GET in case I want some other code to POST it to a different endpoint for emailing, or in case I want to just download the Excel file by hitting the endpoint manually in a browser. It's downloading the Excel file, but when I try to open it I see the message "Excel cannot open the file 'blahblah' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file." After getting that error, I've tried changing the MIME
