OpenXML spreadsheet created in .NET won't open in iPad

Question

I am trying to generate a spreadsheet in .NET which will be opened by my manager on his iPad when he\'s out of the office.

The spreadsheet opens fine on a Windows PC

You could try to validate OpenXML spreadsheet once it's created:

using System;
using System.Collections.Generic;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Validation;

using (OpenXmlPackage document = SpreadsheetDocument.Open(spreadsheetPathToValidate, false))
{
    var validator = new OpenXmlValidator();
    IEnumerable errors = validator.Validate(document);
    foreach (ValidationErrorInfo info in errors)
    {
        try
        {
            Console.WriteLine("Validation information: {0} {1} in {2} part (path {3}): {4}",
                        info.ErrorType,
                        info.Node.GetType().Name,
                        info.Part.Uri,
                        info.Path.XPath,
                        info.Description);
        }
        catch (Exception ex)
        {
            Console.WriteLine("Validation failed: {0}", ex);
        }
    }
}

Hope that helps,
