GridFieldExportButton doesn't apply formatting. I actually try fixing it that way first here before realizing this is probably bad because the exported data may included HTML link hyperlinks which will looks really bad in a csv
So I think the proper solution is don't manipulate data in a formatting function, instead just create some new 'get' methods that do the data manipulation
