Vlookup the responses from a form and add a row to excel

[sushant_mishra]

I am using a Form to collect responses. Now I am able to add it to excel online using trigger as : whenever response is submitted -> apply to each -> add a row . 
The problem is I want to use a mapping file to map the responses of various questions to another value. For example if I get a response as Yes. I want to enter the value as Stargazer. Unfortunately i cannot change the form.
How can I map the responses to different questions using 1 (or more) tables in excel (or a mapping list on sharepoint), before I add a row in my excel.

Thanks.

Hi @sushant_mishra :

Do you want to find the corresponding value of each answer in the mapping file, and then use these values to add new rows?

My method is to traverse the mapping file, compare each answer in the process, and then save the matching results in different variables (each question corresponds to a variable). Then use these variables to add row.I've made a test for your reference:

1\My form

2\My flow

I created the variable "mappingfile" as the mapping file

Reference expression:

1. items('Apply_to_each')['Question']
2. items('Apply_to_each')['Value']
3. items('Apply_to_each')['Question']
4. items('Apply_to_each')['Value']

The Result:
