I have toushand of data from the old system that stored in an spreadsheet file, and now want to migrate the datas to Odoo.

And on the spreadsheet we have tens of sheet, every sheet is contain the same datas. And from table on the sheet, there we must import it to at least 5 differents models.

models:
1. Students

2. Teachers

3. Schedules
4. Registrations
5. Classroom

So, my question is: Is there any importing script available, no worries even if the script is for import data to Odoo default module like Inventory, Sales, Accountg, etc..

Please help, provide sources or tutorial how to do that.

Thanks

Tri
