The Undermine Journal’s IQY Data Source for World of Warcraft Market Prices

If you’re like me, then you’re handsome, famous, and play World of Warcraft. If you’re not like me, then you hate spreadsheets. Don’t worry, I’m here to help you. Now, let’s take a stroll to the forbidden, seedy land of Microsoft Excel and Web Query Files.

The Undermine Journal (UJ) is a great resource for data mining market prices and the economy in World of Warcraft. You can search for an item at a time, or use their canned reports to find various types of deals. One of the many hidden gems UJ has to offer is the availability of market data as a data source. I had been using the CSV format of their market price data, but recently switched to IQY.

IQY is a Web Query File that is nothing more than a text file that includes a data source address for a Web Service or API. The IQY file is then recognized by Microsoft Excel and data returned from the service call is displayed in a worksheet.

Here’s how to generate an IQY file for Excel:

  1. Register an account on The Undermine Journal. You will not have access to the IQY data source unless you are logged in
  2. On the User Controls page, find the “Market Data XML and CSV” section, choose a realm, and click on “Excel Data Source” to access your IQY file
  3. Save and open the IQY file in Excel

Now that you have your data, you can start mining the market locally. While you could certainly use this to simply look up item values for buying and selling, this data is extremely useful for crafting. In my next post, I’ll describe how this process applies to my crafting of Darkmoon Faire cards, and formulas you can use to query the data.
