I am using the closed XML for generating the excel template. After filling the data in the generated excel, I am trying to import the excel with data. It returns error “The specified package is invalid. The main part is missing.” . I am using XLSX file.
try
{
var workbook = new XLWorkbook(FILE_PATH);
}
catch (Exception ex)
{
throw;
}
It throws error when creating object of XLWOrkbook using the excel template generated.
Please provide a solution,
Thanks in Advance…
I got the issue. My file was in the format “Strict Open XML Spreadsheet“. I have changed into “Excel Workbook“. It might be useful for you.
