.csv files can also be opened and then pasted into excel workbooks. Excel is a fun and addictive modeling tool with which you can see what is happening under the hood. It leads to harder tools such as mathcad, maple, and mathematica.
I will post some titles from my excel financial tools library later.
Not meant to be a knock but Google has free historical data for funds, etfs, and stocks which can be downloaded as .csv files for analysis. I am looking for historical options data and welcome leads.
