SAP TAO: Get and Set Value from/to Excel

Hello,

as i do not have any documentation yet, i ask this SAP TAO Question to the community:

Can anybody explain, how i make Getter and Setter from/to Excel Files in SAP TAO?

1. I want to read a value from a excel with TAO and check in SAP if the value in the SAP GUI is the same as in my Excel. e.g. i have a quantity in my excel and i want to check, if the current production order has the same quantity.
2. I want to read a value from a production order with TAO and want to write down this value to the excel with TAO.

These are my 2 use cases, i want to do with TAO.

Any help will be appreciated.

Regards,

Sebastian
