Waleed, thanks for your answer.

It sounds a little too technical for me at this time, but I'll look into it and try the method suggested.

Thanks again!

Hello,

The state field is read only and you will not see it in the available fields in import screen:

state = fields.Selection([
    ('draft', 'Quotation'),
    ('sent', 'Quotation Sent'),
    ('sale', 'Sales Order'),
    ('done', 'Locked'),
    ('cancel', 'Cancelled'),
    ], string='Status', readonly=True, copy=False, index=True, track_visibility='onchange', default='draft')

My suggestion is to create a new module and override create method to confirm each quotation as below and after install the module, try to import your quotations. (I didn't test and I believe it will work and it's worth to give it a try in Test Environment and let us know the results) 

    @api.model
    def create(self, vals):
        result = super(SaleOrder, self).create(vals)
        result.action_confirm()
        return result 

 But you already imported them and you want to confirm them all to sale, you can create a module to override write method as below and after install the module, try to import your quotations. (I didn't test and I believe it will work and it's worth to give it a try in Test Environment and let us know the results) 

   @api.multi
   def write(self, values):
    result = super(SaleOrder, self).write(values)
    result.action_confirm()
    return result
