问题
Below shows the highlighted cell which display as - (hyphen) but actually has 0 value inside it.
It's a formula cell with following custom formatting.
It's a formula cell but when the result is 0, it displays as -.
My requirement is to fetch - instead of 0.
cell2Update = sheet.getRow(4).getCell(3);
cell2Update.setCellType(Cell.CELL_TYPE_NUMERIC);
System.out.println(cell2Update.getStringCellValue());//Exception
System.out.println(cell2Update.getNumericCellValue());//Display as 0
Please help me with this doubt. I want to display the value which is displayed in Spreadsheet (-).
回答1:
Do using a DataFormatter as shown in Getting the cell contents. And because the value might be result of a formula. Do using using a DataFormatter together with a FormulaEvaluator:
...
DataFormatter formatter = new DataFormatter();
FormulaEvaluator evaluator = workbook.getCreationHelper().createFormulaEvaluator();
...
cell2Update = sheet.getRow(4).getCell(3);
...
String value = formatter.formatCellValue(cell2Update, evaluator);
System.out.println(value);
...
