func (Cell) Type

func (c Cell) Type() CellType

Type returns the CellType of the value.

func (Cell) URL

func (c Cell) URL() (*url.URL, bool)

URL returns the parsed URL when a cell contains a hyperlink.

func (Cell) Value

func (c Cell) Value() interface{}

Value returns the contents as a generic interface{}.

type CellType

type CellType uint16

CellType annotates the type of data extracted in the cell.

const (
	BlankCell CellType = iota
	IntegerCell
	FloatCell
	StringCell
	BooleanCell
	DateCell

	HyperlinkStringCell // internal type to separate URLs
	StaticCell          // placeholder, internal use only
)

CellType annotations for various cell value types.

func (CellType) String

func (c CellType) String() string

String returns a string description of the cell data type.

type FmtFunc

type FmtFunc func(*Formatter, interface{}) (string, interface{})

FmtFunc will format a value according to the designated style. It also returns the parsed value.

type Formatter

type Formatter struct {
	// contains filtered or unexported fields
}

Formatter contains formatting methods common to Excel spreadsheets.
