xlsxtra - extra utilities for xlsx

This was developed as an extension for the xlsx package. It contains the following utilities to manipulate excel files:

• Sort(), SortByHeaders: multi-column (reverse) sort of selected rows (Note that columns are one based, not zero based to make reverse sort possible.)
• AddBool(), AddInt(), AddFloat(), ...: shortcut to add a cell to a row with the right type.
• NewStyle(): create a style and set the ApplyFill, ApplyFont, ApplyBorder and ApplyAlignment automatically.
• NewStyles(): create a slice of styles based on a color palette
• Sheets: access sheets by name instead of by index
• Col: access cell values of a row by column header title
• SetRowStyle: set style of all cells in a row
• ToString: convert a xlsx.Row to a slice of strings

Example

Add cells and retrieve cell values by column title header:

type Item struct {
	Name   string
	Price  float64
	Amount int
}
sheet, err := xlsx.NewFile().AddSheet("Shopping Basket")
if err != nil {
	fmt.Println(err)
	return
}

// column header
var titles = []string{"item", "price", "amount", "total"}
header := sheet.AddRow()
for _, title := range titles {
	xlsxtra.AddString(header, title)
}
style := xlsxtra.NewStyle(
	"00ff0000", // color
	&xlsx.Font{Size: 10, Name: "Arial", Bold: true}, // bold
	nil, // border
	nil, // alignment
)
xlsxtra.SetRowStyle(header, style)

// items
var items = []Item{
	{"chocolate", 4.99, 2},
	{"cookies", 6.45, 3},
}
var row *xlsx.Row
for i, item := range items {
	row = sheet.AddRow()
	xlsxtra.AddString(row, item.Name)
	xlsxtra.AddFloat(row, item.Price, "0.00")
	xlsxtra.AddInt(row, item.Amount)
	xlsxtra.AddFormula(row,
		fmt.Sprintf("B%d*C%d", i+1, i+1), "0.00")
}

// column Col type
col := xlsxtra.NewCol(header)
price, err := col.Float(row, "price")
if err != nil {
	fmt.Println(err)
	return
}
fmt.Println(price)
// Output: 6.45

Multi column sort:

sheet, err := xlsxtra.OpenSheet(
	"xlsxtra_test.xlsx", "sort_test.go")
if err != nil {
	fmt.Println(err)
	return
}

// multi column sort
xlsxtra.Sort(sheet, 1, -1,
	3,  // last name
	-2, // first name
	6, // ip address
)
for _, row := range sheet.Rows {
	fmt.Println(strings.Join(xlsxtra.ToString(row), ", "))
}
fmt.Println()
// by header
headers := xlsxtra.NewHeaders(sheet.Rows[0])
err = xlsxtra.SortByHeaders(sheet, 1, -1, headers,
	"-amount",
	"first_name",
)
if err != nil {
	fmt.Println(err)
	return
}
for _, row := range sheet.Rows {
	fmt.Println(strings.Join(xlsxtra.ToString(row), ", "))
}

// Output:
// id, first_name, last_name, email, gender, amount
// 9, Donald, Bryant, [e-mail], Female, 100000000
// 7, Donald, Bryant, [e-mail], Male, 3000000
// 10, Donald, Bryant, [e-mail], Male, € 9
// 4, Teresa, Hunter, [e-mail], Female, 6000
// 5, Joshua, Hunter, [e-mail], Male, 50000
// 8, Jacqueline, Hunter, [e-mail], Female, 20000000
// 2, Harry, Hunter, [e-mail], Male, 80
// 6, Rose, Spencer, [e-mail], Female, 400000
// 1, Jimmy, Spencer, [e-mail], Male, 9
// 3, Benjamin, Spencer, [e-mail], Male, 700
//
// id, first_name, last_name, email, gender, amount
