Question

My data is stored in a format(look down): [-] means a blank cell, on the right may be only 10 columns, after the space. Something like this:
[string0]

Answer 1

If I am clear you just want to filter your first column string and rest seperately.

Why not you just use a simple counter for this:

 while(rowIterator.hasNext()) {
    Row row = rowIterator.next();
    String RowContent = null;
    Iterator cellIterator = row.cellIterator();
    while(cellIterator.hasNext()) {
        Cell cell = cellIterator.next();
        RowContent=RowContent+cell.toString();
    }
    //Code for saving RowContent or printing or whatever you want for text in complete row
}

RowContent will give concatenation of each cells of a single row in each iteration.
