Functions

func FileToSlice 

func FileToSlice(path string) ([][][]string, error)

A convenient wrapper around File.ToSlice, FileToSlice will return the raw data contained in an Excel XLSX file as three dimensional slice. The first index represents the sheet number, the second the row number, and the third the cell number.

For example: 

var mySlice [][][]string
var value string
mySlice = xlsx.FileToSlice("myXLSX.xlsx")
value = mySlice[0][0][0]

Here, value would be set to the raw value of the cell A1 in the first sheet in the XLSX file.

func HSLToRGB 

func HSLToRGB(h, s, l float64) (r, g, b uint8)

HSLToRGB converts an HSL triple to a RGB triple.

func RGBToHSL 

func RGBToHSL(r, g, b uint8) (h, s, l float64)
