How to search/read field by label Name



I have an excel sheet, where in a column multiple data is populated row wise, like if column is a, so in in column ‘a’ we have 10 rows,and row has some data, e.g. row 1-name , row 2-emp id row 3- city and so on. I wanted to read the data by label name like, by name, emp id and city and so on.

I can’t read it by cell no as data is dynamic since in my future enhancement cell no can be change, and after read data by label name from sheet , I have search same contact in a web page, so that it can match and pass the results.

How can I achieve that?
