I'm currently using libreoffice and Google office for my day to day office needs. It frustrates me that it does not directly integrate into Odoo. (Working on solution)

I have recently found CollaboraOffice which is basically a online version of libreoffice designed to integrate into something like odoo Document.

I have two questions. 

1. Does anyone have experience with Collabora to get an idea of the effort it would take to integrate collabora with Odoo Document.

2. How hard would it be to add the odoo function into libre office, or collabora. (So I can pull data directly from Odoo into my spreadsheet)?
