However, Word is actually better at dealing with PDF tables. Previously in the article Excel Getting Data From the Web Iâve explained how you can use Query Tables to import data from the web into an excel worksheet.

They provide a nice easy way to collate documents from different sources for distribution. I must however point out a slight typo in the formulas used in the mandelbrot iteration : the correct formula to calculate Ynew should be 2* Xold * Yold + Y_orig and not 2*Xold^2 * Yold^2 + y_orig (just remove the square). Wish I'd had it for an assay analysis we did a while ago. In this article I will explain how to retrieve data from a website using a query table and VBA.
