Mapping the inputs and outputs on your Excel file are a pre-requisite for creating an API. This process doesn't take too long. Just follow along!
Find the Name Manager
Open your Excel file
Go to the Formulas tab
Click on "Define Name" (on a Mac) / "Name Manager" (on a Windows)
You will see a dialog box open
To name your API request parameters, select the value cell for your input to name them. There are two ways of mapping your inputs.
Syntax: Xinput_[parameter] and Xoutput_[parameter]
We used the Name Box in Excel to identify 'a' and 'b' as inputs. The name must be prefixed with Xinput_. In this example, we are using individual cells and range inputs for Spark.
Note that the ranged value must have a header row that is completed. It is strongly advised that heading titles begin with with an alphabetic character.
Similarly, for outputs, identify your outputs and prefix the name with Xoutput_.
