Thanks for your query.
I have tried the scenario using following sample code but no problem is observed as spreadsheet created by EPPlus is successfully read by Aspose.Cells.
Please share your sample file and code snippet with us for our testing. We will reproduce the problem and provide our feedback after analysis.
Following is the sample code which is used for testing:
static void Main(string args)
Console.WriteLine("Creating XLSX file using EPPlus");
Console.WriteLine("Success in creating XLSX file using EPPlus");
Console.WriteLine("Success in reading XLSX file using EPPlus");
static void CreateExcelFileInEpplus()
var newFile = new FileInfo("output.xlsx");
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
// do work here
static void ReadExcelFileUsingAsposeCells()
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook("output.xlsx");
