I have already tried that. While i have yet to write an XML schema to go along with my data, I don't think that excel's XML support allows a single XML file to be translated into multiple worksheets, which is what I would like to do. Since I wrote that program, I could do that. However, I think that the same problem applies that the XML file is causing: Excel interprets a single CSV file as a single worksheet. Since my data has more than 2 dimensions (Statistic Name, Run, Step) and I have tens of runs with hundreds of steps, dropping it all in a single worksheet would make working with data pretty hard. I had not thought of that idea. I will look into it, unfortunately my VBA skills are close to zero. thanks for your ideas, I appreciate your input. Greg
