Created attachment 29430 [details] xlsx document for reproducing issue The attached xlsx document has been created with Excel 2010. Using the following code to force formula recalculation does not work, i.e. when the document is opened the formula value is not updated: Workbook wb = WorkbookFactory.create(new File("recalc2.xlsx")); wb.getSheet("Sheet1").setForceFormulaRecalculation(true); wb.write(new FileOutputStream("out.xlsx")); setForceFormulaRecalculation seems to work ok with xlsx documents created in Excel 2007.
Should be fixed in r1394059 setForceFormulaRecalculation didn't work because it conflicted with calculation settings in workbook.xml. If workbook-level setting is"manual" then Excel does not recalculate formulas, no matter if formulaRecalculation=true in the sheet. Please try with the latest build from trunk. Yegor
