Types

type Spreadsheet

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

Spreadsheet represents the whole .xlsx file.

func OpenFile

func OpenFile(path string) (*Spreadsheet, error)

OpenFile reads a file located at the given path and returns a spreadsheet object.

func (*Spreadsheet) GetWorksheet

func (s *Spreadsheet) GetWorksheet(number int) (*Worksheet, error)

GetWorksheet returns the worksheet with the given number, starting at 0.

func (*Spreadsheet) NumWorksheets

func (s *Spreadsheet) NumWorksheets() int

NumWorksheets returns the number of worksheets in a file.

type Worksheet

type Worksheet struct {
	Name      string
	MaxRow    int
	MaxColumn int
	MinRow    int
	MinColumn int
	// contains filtered or unexported fields
}

Worksheet represents a single worksheet in an excel file. A worksheet is a rectangular area of cells, each cell can contain a value.

func (*Worksheet) Cell

func (ws *Worksheet) Cell(column, row int) string

Cell returns the contents of cell at column, row, where 1,1 is the top left corner. The return value is always a string. The user is in charge to convert this value to a number, if necessary. Formulae are not returned.

func (*Worksheet) Cellf

func (ws *Worksheet) Cellf(column, row int) (float64, error)

Cell returns the contents of cell at column, row, where 1,1 is the top left corner. The return value is always a float64 and an error code != nil if the cell contents can't be decoded as a float.
