Read whole/entire column at once from CSV


I was wandering if there is any mechanism that allows to read the hole column from e.g. CSV file at once. I know I can iterate through with use of loops, but I would like to avoid that, since I will have a lot of data (rows) . Is there any feature that allows me to grab the hole column (data in it), and e.g. gives me back the array list of cells or something like that ?

I know that I can do somehting like that:
Column column = new Workbook().get(0).getCells().getColumn(0); // BTW it is deprecated
But I can not get any data from this object. I guess I can use it for changing the style.

Any help would be appreciated,

I am using JAVA and AsposeCells 7.3.1


Thanks for your query.

I think you may try to use Cells.exportArray() method if it suits your needs, see the sample code segment below for your reference:
Sample code:

int numCol =1;
Object dataTable [][] = worksheet.getCells().exportArray(0,0, numRows,numCol);
//Printing array
for(int r = 0; r < numRow; r++)
    for(int c = 0; c < numCol; c++)

Hope, this helps a bit.

Than you for the solution, but I think that for CSV file it will not work that fine…When I use code above it actually reads hole row with all ’ ; '. So e.g. in my file I have:

And in final result I would like to have [123,235,567] - hole first column. Your code works fine for excel reading, but not for CVS. Do you have how I could improve it?


I had you set the load options:

    TxtLoadOptions opts = new TxtLoadOptions();

thanks you for your help! :slight_smile:
