Sheet View (or integrate Sheet View) in Suite CRM

Is there any possibility to switch to Sheet View (or integrate Sheet View) in Suite CRM
like this

So I mean can anyone have met with the problem of mass creation of new records? something like direct database editing via suitecrm interface. but much more extensive than a mass update

The easiest approach to this is to create the required contacts/opportunities etc in a spreadsheet, and then import the file you create.

e.g. Click on opportunities, and select Import Opportunities. You then have the ability to Download Import File Template. You can then follow the instructions and fill out the template as desired before importing the data that you want to add.
