Class XSSFCell

java.lang.Object
org.apache.poi.xssf.usermodel.XSSFCell
All Implemented Interfaces:
Cell

public final class XSSFCell extends Object implements Cell
High level representation of a cell in a row of a spreadsheet.

Cells can be numeric, formula-based or string-based (text). The cell type specifies this. String cells cannot contain numbers and numeric cells cannot contain strings (at least according to our model). Client apps should do the conversions themselves. Formula cells have the formula string, as well as the formula result, which can be numeric or string.

Cells should have their number (0 based) before being added to a row. Only cells that have values should be added.

    • setCellValue

      public void setCellValue(Date value)
      Set a date value for the cell. Excel treats dates as numeric so you will need to format the cell as a date.
      Specified by:
      setCellValue in interface Cell
      Parameters:
      value - the date value to set this cell to. For formulas we'll set the precalculated value, for numerics we'll set its value. For other types we will change the cell to a numeric cell and set its value.
    • setCellValue

      public void setCellValue(Calendar value)
      Set a date value for the cell. Excel treats dates as numeric so you will need to format the cell as a date.

      This will set the cell value based on the Calendar's timezone. As Excel does not support timezones this means that both 20:00+03:00 and 20:00-03:00 will be reported as the same value (20:00) even that there are 6 hours difference between the two times. This difference can be preserved by using setCellValue(value.getTime()) which will automatically shift the times to the default timezone.

      Specified by:
      setCellValue in interface Cell
      Parameters:
      value - the date value to set this cell to. For formulas we'll set the precalculated value, for numerics we'll set its value. For othertypes we will change the cell to a numeric cell and set its value.

      cellType -
      evalWb - BaseXSSFEvaluationWorkbook already in use, or null if a new implicit one should be used
    • toString

      public String toString()
