How to increment values each of the time for website extract data table

Hi @Yoichi

Below is my Web extract data screen from Website.

There will be few rows and I have to find the data from Excel to check here if available.
IF the data is available on any one row then have to update something on excel “Matched” and if not then “Not Matched”.
Then have to go for next record of excel and search it on website , repeat same process to match excel data with Web.

Now Que is if no lines matched and going to next record of excel then rowindex is continue from there . I want to start each record with row index 2 .

EX: for above picture row index are 2, 5, 8 and for next record it is coming as 11 but it should be 2 again if there is new record.

Thanks
