Method Details

getNumericCellValue

public static double getNumericCellValue(Cell _cell)

Get the value of the cell as a number.

For strings we throw an exception. For blank cells we return a 0. For formulas or error cells we return the precalculated value;

Returns:

the value of the cell as a number

Throws:

IllegalStateException - if the cell type returned by #getCellType() is CELL_TYPE_STRING

NumberFormatException - if the cell value isn't a parsable double.

See Also:

• for turning this number into a string similar to that which Excel would render this number as.

typeMismatch

public static RuntimeException typeMismatch(int expectedTypeCode,
 int actualTypeCode,
 boolean isFormulaCell)

Used to help format error messages

getCellType

public static int getCellType(Cell _cell)

Return the cell type.

Returns:

the cell type

See Also:

• Cell#CELL_TYPE_BLANK
• Cell#CELL_TYPE_NUMERIC
• Cell#CELL_TYPE_STRING
• Cell#CELL_TYPE_FORMULA
• Cell#CELL_TYPE_BOOLEAN
• Cell#CELL_TYPE_ERROR

getCellStyle

public static CTCellStyle getCellStyle(Cell _cell)

Return the cell's style.

Returns:

the cell's style.

getNumberFormatIndex

public static long getNumberFormatIndex(Cell _cell)

Get the index of the number format (numFmt) record used by this cell format.

Returns:

the index of the number format

getNumberFormatString

public static String getNumberFormatString(Cell _cell)

Get the contents of the format string, by looking up the StylesSource

Returns:

the number format string

getDateCellValue

public static Date getDateCellValue(Cell _cell)

Get the value of the cell as a date.

For strings we throw an exception. For blank cells we return a null.

Returns:

the value of the cell as a date

Throws:

IllegalStateException - if the cell type returned by #getCellType() is CELL_TYPE_STRING

NumberFormatException - if the cell value isn't a parsable double.

See Also:

• for formatting this date into a string similar to how excel does.

getBooleanCellValue

public static boolean getBooleanCellValue(Cell _cell)

Get the value of the cell as a boolean.

For strings, numbers, and errors, we throw an exception. For blank cells we return a false.

Returns:

the value of the cell as a boolean

Throws:

IllegalStateException - if the cell type returned by #getCellType() is not CELL_TYPE_BOOLEAN, CELL_TYPE_BLANK or CELL_TYPE_FORMULA
