I use this link to copy all the pricing data from the GW2Spidy site into a text file:
http://www.gw2spidy.com/api/v0.9/csv/all-items/all
Then, I import this into Excel 2010. When I am ready to refresh the data after downloading it again from the website, I select the whole page and hit `delete`. When I do this, I get a message from Excel warning me that the data contains a query, and it wants me to confirm that I will be deleting the query.
So, my question for tech mavens is this: what query is this? Is there something embedded in this data that might allow me to have the page refresh itself from the site without me having to manual download and import it?
