google scraper code

I'm using a google scraper code, which i'm including, to pull top 50 results for a specific search terms.
It dumps the information into a google excel doc .
how can i adjust the code, that instead of giving me the top 50 results, it should split the results to give me just results 1-10, then 11-20, then 21-30 etc.
so I will be able to track better exactly which page the results came from.

If it goes to excel, can't you just add a column that works out the page number from the position?

That’s the least of my problems. The main thing is to get the top 50 search results in a spreadsheet broken up by page.

I proposed it as an answer to your problems.

Instead of hacking into this code, why not solve it in the spreadsheet. I'm sure it's a lot easier to create a column where it's value is based on the row number divided by 10?
