I am not a programmer but I can modify code. What I am in need of is a generic script that I can modify with specifics to (1)reload a page every x minutes (2)scrape data from a table (3) update a local csv file.

Is anyone willing to do this?

1) yes
2) yes
3) no

What good is scraping data if you can't save it.

JS can't save file, JS is bound and limited inside a browser (in this case). You need a more powerful language like C,C++,C# or JAVA.

hey, don't you know iMacros? Check the firefox extensions site.

You can upload a string or a query string if you wish, but that's all you can do.

Or you could use a perl script on a cronjob/scheduled task that does 1, 2, and 3.
