I have done application using Extjs 4. I have requirement need to export grid data to excel. I have grid it contains many records, showing records by group headers/summary(collapse/Expand actions ). The same thing i need to export grid data to excel the same activity need collapse/expand in excel sheet. I have tried i am able to export grid records with group headers.summary to excel, cool it is working but collapse/expand is not happening in excel sheet. I need to implement this feature by writing a code. Can anybody tell me how to achieve this one? is it possible or not by using extjs? great appreciated. Thank you.
Something like this doesn't come out of the box. There is however some exporter from ExtJS to Excel: http://www.sencha.com/forum/showthread.php?136598-Export-store-to-Excel
We we internally do is generate our Excel backend with .NET so we have more control.
