问题 I want to select a range from the first to the last cell filled in the row or column. In VBA the code stays as below using xlDown or xlToRight.

问题 I am trying to open an XLSX file as a template (I have even used a blank XLSX file), using EPPLUS 4.0.3. If I do not open the template file (blank or the real one) and just create a new workbook and create a sheet, it works fine. OR if I open the template file, and create a NEW worksheet, then it works fine. It is only when I try to access the FIRST sheet in the template that I get the error: Worksheet position out of range. Accessing the first worksheet like this: workBook.Worksheets.First()

问题 Good morning, I would like to edit some cells from already existing excell file. I tried use EPPlus and normal OpenXml classes. However I failed.

Trial 1 - EPPlus: MemoryStream memoryStream = new MemoryStream(); using (var fs = new FileStream(@"Path\Test.xlsx", FileMode.Open, FileAccess.Read)) { byte[] buffer = new byte[1024]; int bytesRead = 0; while ((bytesRead = fs.Read(buffer,

问题 I'm using the following code to convert an Excel to a datatable using EPPlus: public DataTable ExcelToDataTable(string path) { var pck = new OfficeOpenXml.ExcelPackage(); pck.Load(File.OpenRead(path)); var ws = pck.Workbook.Worksheets.First(); DataTable tbl = new DataTable(); bool hasHeader = true; foreach (var firstRowCell in ws.Cells[1, 1, 1, ws.Dimension.End.Column]) { tbl.Columns.Add(hasHeader ? firstRowCell.Text : string.Format("Column {0}", firstRowCell.Start.Column)); } var startRow =

问题 EPPlus has no support for extLst thing which is needed to make databars conditional formatting with solid fill. They are gradient by themselves without modifications. I coded this to modify worksheet's xml directly (this gets databars from worksheet XML and then adds required extLst nodes): public static Random Rnd = new Random(); public static string GenerateXlsId() { //{29BD882A-B741-482B-9067-72CC5D939236} string id = string.Empty; for (int i = 0; i < 32; i++) if (Rnd.NextDouble() < 0.5)
