I have gone through many questions posted here and referred POI documentation too, but i am not able to resolve this issue.
Issue: When trying to re-calculate the formula i am getting an exception.
Formula:
=CONCATENATE("#DFLT=",COUNTIF(C5:C390,"=DEFAULTERS"),"; #NP=",COUNTIF(C5:C390,"=NOT PAID"),"; #PCsh=",COUNTIF(C5:C390,"=Paid Cash"),"; #PChk=",COUNTIF(C5:C390,"=Paid Cheque"),"; #PNeft=",COUNTIF(C5:C390,"=Paid Neft"))
Exception:

I made following attempts to re-calculate formula:
// ExcelFile.workbook.getCreationHelper().createFormulaEvaluator().evaluateAll();
// HSSFFormulaEvaluator.evaluateAllFormulaCells(ExcelFile.workbook);
for (Row r : sheet) { for (Cell c : r) { if (c.getCellType() == Cell.CELL_TYPE_FORMULA) { System.out.println("Evaluating formula for cell = " + c.getCellFormula()); evaluator.setDebugEvaluationOutputForNextEval(true); evaluator.evaluate(c);
After enabling the poi logs i found that the cell on which
=CONCATENATE("#DFLT=",COUNTIF(C5:C390,"=DEFAULTERS"),"; #NP=",COUNTIF(C5:C390,"=NOT PAID"),"; #PCsh=",COUNTIF(C5:C390,"=Paid Cash"),"; #PChk=",COUNTIF(C5:C390,"=Paid Cheque"),"; #PNeft=",COUNTIF(C5:C390,"=Paid Neft"))
was dependent, were also excel formula.
=CONCATENATE(" {",HZ5," - ",IA5,"}, ","{",IB5,,"}")
This formula had an extra comma(,), Which was causing an MissingArgument while parsing the formula, and while evaluating this Missing Argument results in IllegalArgumentException.
POI logs showed:
10-30 16:56:18.377: I/System.out(26511): [POI.FormulaEval]I * ptg 7: org.apache.poi.ss.formula.ptg.MissingArgPtg [ ]
10-30 16:56:18.377: I/System.out(26511): [POI.FormulaEval]I = org.apache.poi.ss.formula.eval.MissingArgEval@42be7f58
POI can now evaluate formulas which apply the range operator to area refs.
However, POI still cannot parse these formulas. For example, these calls will fail:
cell.setCellFormula("AVERAGE(J6:OFFSET(I6,0,DAY(TODAY())-1))");
cell.setCellFormula("SUM((C1:D2):(D2:E3))");
