I want to check whether the cell is merged, If merged how do i get the value of its parent cell, ?
Please use the Cell.isMerged() method for your needs.
Once, you know the cell is a merged cell, then you can get merged cell range using the Cell.getMergedRange() method.
If you want to know all merged cells in a worksheet then use Worksheet.getCells().getMergedCells() method.
Thanks a lot Shakeel
