    Hi,

    I have tried and found the solution you shared did not help us.

    When user import excel first time it works fine but whenever user tries to upload same excel with different data or same data it unable read few columns specifically DATETIME type columns and throws null reference error on following line:-

    cellValue = formatter.FormatCellValue(worksheet.GetRow(row).GetCell(column));

    Hi @smartlayer Since your DateFormatter implementation does not exist in zero, I can not try to produce your problem. The current implementation is a little bit different(see here: https://github.com/aspnetzero/aspnet-zero-core/blob/5e9ca60d4f3710f3cbe40340362ed542d7ebcaf4/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Application/Authorization/Users/Importing/UserListExcelDataReader.cs#L80-L100). Can you please check if it suits your requirements? If not, can you please share your implementation so that I can try it?
