POI doesn't provide RowDifferences/ColumnDifferences functionality out
of the box, but it does provide a formula parser so that you can
compare parsed expressions and decide whether they match.
Here is an example:
HSSFWorkbook workbook = ...;
HSSFEvaluationWorkbook fpb = HSSFEvaluationWorkbook.create(workbook);
Ptg[] ptg_d4 = FormulaParser.parse("C3+2", fpb, FormulaType.CELL, -1);
// RefPtg,IntPtg,AddPtg
Ptg[] ptg_d5 = FormulaParser.parse("C4+2", fpb, FormulaType.CELL, -1);
// RefPtg,IntPtg,AddPtg
The formula parser return tokens in the Reverse polish Notation Order,
i.e. for C3+2 it will return "C3","2","+"
