dear all , I have bought a file in txt format . It is a intraday 1 minute historical futures data for several years . I hope to open it in spread sheet software so I can do some statistic work to work for . But when I use excel to open it , I found that my excel ( version 2002 ) cannot open such quantity of rolls , more than 65536 . I have spss and open office 3.0 but seems both cannot open it in a spread sheet . Can someone tell me how to do it . Is other newer version of excel can do it ? Thanks a lot in advance .
