    Default JExcelAPI

    Hi there,

    I'm doing a Java application that allows users to input the range (eg. A1:B3) of the excel sheet they wish to get the data from. Then the program will read the content and output it. I'm using JExcelAPI and Eclipse.

    I'm having problem with the ranges as there is not examples or tutorials on ranges.

    Thankyou.

    I have only used Apache POI briefly a few years ago but not familiar with JExcel. However I think there is no way to extract the data from the specified range. What you would have to do is retrieve the desired rows and then the desired cells within those rows. But I could be wrong.

    I used JExcel long ago. I now use SmartXLS. If you can ignore the fact that you have to either purchase it or redownload the trial every 60 days, I would suggest going to that since you'll have MUCH more capability with Excel.

    Keep in mind that with JExcel, Ranges are not things like: A1:B3. Ranges are named ranges in Excel (opposed to just a range of cells). So if you're using the Range class, that is not what I think you are trying to do.

    My suggestion would be to call the Sheet's getCell() method and get each individual cell in the range.

    Thanks for the reply. Is it possible to give me an example using Apache POI?

    So by using Sheet's getCell(), I'd be able to get the data values of the cells right?

    Well, if I am correct (which I'm not 100% sure I am):
    You call the Sheet's getCell() method. You can send this method either 2 ints (column and row) or a String representation of the desired cell (ex: A5). This method will then return a Cell Object. You then invoke Cell.getContents() method and it will return a String representing what is in the cell.

    To get a range of cell data (such as A1:B3), I would create my own method that goes through all the cells in that range, gets the data and stores it in a 2d array, and then returns the 2d array. It seems dumb that isn't already a method in the library, but whatever.
