I have a big problem with Apache POI.
A B C D
1 text text text text
2 comment
3 text text text text
In this example row 2 is empty, C2 has no text, but a comment.
If I want to get row 2, POI will return null.
How can I get a comment from an empty cell in an empty row?
To fetch arbitrary comments, without going via the Cell directly, you can use Sheet.gteCellComment(int row, int cell)
From your example, to get the comment in C2, do something like:
CellReference ref = new CellReference("C2")
Comment commentC2 = sheet.getCellComment(ref.getRow(), ref.getCol());
