Up until now, the collaborative expected a field named `raw` containing the serialized json data. This is historic and appeared because the field containing the existing field `raw` on `document.document` contained this data. The name `raw` is meaningless. Now the collaborative expects a field named `spreadsheet_data`. I chose a field over a custom method because fields are more broadly supported everywhere (web client services, web client mocks) closes odoo/odoo#104167 Related: odoo/upgrade#4005 Related: odoo/enterprise#33246 Signed-off-by: Rémi Rahir (rar) <rar@odoo.com>
