It may help you.

I have attatched an xlsx document in CRM 4.0, and it has been created in tabel: annotation.
Now i would like to make use of this annotation in my code. Need to access a sheet within this file and use the data to update other entities i CRM.

I have retrievde the annotation by the objectid.
and decoded the content of documentbody (a string) using Convert.FromBase64String, and have now a byte-array.
My question is what to do next, in order to re-create the xlsx file in-memory ?
Any suggestions ?

Just thinking how can you achieve this. You can even introduce your own tab on the form as Notes and then add iframe and aspx page to enter/read text using rich text box. when submit simply add this text as note to the entity using CRM sdk. So there are endless possibilities. But if you are desinging a complex solution or vertical, i recommend to use supported ways as upgrade will cost a lot in case of unsupported customization.
