With workbook.setForceFormulaRecalculation(true); is new file correctly saved. All cells have new values!
Next problem: bad output for new file. ------------------------------------------------------------------------------------------------- Formula is: C34 cell.getCachedFormulaResultType(): 0 0. case Cell.CELL_TYPE_NUMERIC --> Last evaluated as: 407.2521754511886 Formula is: C34 cell.getCachedFormulaResultType(): 5 5. case Cell.CELL_TYPE_ERROR --> ------------------------------------------------------------------------------------------------- Why CELL_TYPE_ERROR ? All cells have new values in new file...
