bhuber <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEEDINFO |NEW --- Comment #2 from bhuber <[email protected]> --- @Nick Burch Yes the private method "Format createFormat(double cellValue, int formatIndex, String sFormat)" does exactly do what i need. My use-case is the following: I need to import Excel-files that are huge, and therefore i need to use the "XSSF and SAX Event API" for memory-reasons (save HEAP-memory). Numbers are saved by Excel als Floating-point values like this: 62.474099999999993 We have a convention for our software that all BigDecimals that we save into our database need to have precision of max. 9 digits before the fraction and max. 7 digits after the fraction. As you see, the above number has 15 digits after the fraction which is too long. As i do not want to deal with floating-point problem at all i just want to parse the number as it is shown to the user in the Excel-GUI. To do this with apache-poi i can call the function DataFormatter.formatRawCellContents(..) which gives me the following value for the above example: 62,474 As you see the decimal separator is a comma (,). I need to replace the decimal separator of the excel-format with the decimal-separator of BigDecimal so i can use BigDecimal with this value. But because the decimal-separator of the excel-format is specific to the country i can not just replace it. I need to find out the decimal-separator of the format like follow, and replace it with a dot (.). String xlsxValue = formatter.formatRawCellContents( Double.parseDouble(cellValue.getValue()), cellValue.getFormatIndex(), cellValue.getFormatString()); CellStyle style = new CellStyleHack( cellValue.getFormatIndex(), cellValue.getFormatString()); Cell cell = new CellHack(Double.parseDouble(cellValue.getValue()), style); java.text.Format format = dataFormatter.createFormat(cell); if (format instanceof DecimalFormat) { DecimalFormat decimalFormat = ((DecimalFormat) format); char dSep = decimalFormat.getDecimalFormatSymbols().getDecimalSeparator(); char gSep = decimalFormat.getDecimalFormatSymbols().getGroupingSeparator(); String cSymbol = decimalFormat.getDecimalFormatSymbols().getCurrencySymbol(); String posPre = decimalFormat.getPositivePrefix(); String posSuf = decimalFormat.getPositiveSuffix(); String negPre = decimalFormat.getNegativePrefix(); String negSuf = decimalFormat.getNegativeSuffix(); // java always expects '.' as decimal seperator for BigDecimal and Double. xlsxValue = xlsxValue.replace("" + gSep, ""); xlsxValue = xlsxValue.replace(dSep, '.'); if (cSymbol != null) { // remove € xlsxValue = xlsxValue.replace(cSymbol, ""); } if (posPre != null) { // remove % xlsxValue = xlsxValue.replace(posPre, ""); } if (posSuf != null) { // remove % xlsxValue = xlsxValue.replace(posSuf, ""); } if (negPre != null) { // remove % xlsxValue = xlsxValue.replace(negPre, ""); } if (negSuf != null) { // remove % xlsxValue = xlsxValue.replace(negSuf, ""); } xlsxValue = xlsxValue.trim(); } return xlsxValue; -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
