    Do google searches for APACHE POI and for POIUTILITY.CFC, but I do not know if that is a better solution for what you are trying to do.

    Define 'huge'.  What have you tried so far?  Are you experiencing errors due to the size of the dataset, or just haven't done anything yet and want to know what's the best option?

    With 'huge' what I meant to say here is the excel file which I wanna read contains more than 1000 rows.I didnt try with any thing , but as far as I know using CFSPREADSHEET will take long time. SO I am looking for a better option to achieve this.

    Thanks

    If you're only talking about a couple of thousand rows, then CFSPREADSHEET should be fine.  I read that size spreadsheets all the time, with no problems. If you're talking about tens or hundreds of thousands of rows, then it will get slower, but should still be ok.  The POI cfc works well, but in the end that data needs to be put into a query object no matter which path you take, so be sure that memory is not a factor for the size of data you are reading.  If you start writing large spreadsheets, you will find that CFSPREADSHEET has problems with performance.  In those cases I ended up creating CSV files that people would open in Excel.
