Libxls for GO

GO-xls

GO wrapper for libxls. Read old Excel files (.xls) from GO.

Install

1. install libxls
2. add CGO_LDFLAGS=-lxlsreader to go build / go test command.

See /example/Dockerfile as example of installing required dependencies.

Example

	import "github.com/godzie44/go-xls/xls"


	wb, err := xls.OpenFile(someFile, "UTF-8")
	if err != nil {
		log.Fatal(err)
	}
	defer wb.Close()

	sheet, err := wb.OpenWorkSheet(0)
	if err != nil {
		log.Fatal(err)
	}
	defer sheet.Close()

	for _, row := range sheet.Rows {
		for _, cell := range row.Cells {
			fmt.Println(cell.Value.String())
		}
	}

Or more specialized cell parsing:

	//...

	for _, row := range sheet.Rows {
		for _, cell := range row.Cells {
                        switch v := cell.Value.(type) {
                        case *BlankValue:
                            fmt.Printf("%T no val \n", v)
                        case *FloatValue:
                            fmt.Printf("%T %f \n", v, v.Val)
                        case *BoolValue:
                            fmt.Printf("%T %t \n", v, v.Val)
                        case *ErrValue:
                            fmt.Printf("%T %d \n", v, v.Code)
                        case *StringValue:
                            fmt.Printf("%T %s \n", v, v.Val)
                        case *UnknownValue:
                            fmt.Printf("%T %s \n", v, v.Val)
                        }
		    }
		}
	}

Also, use make example command for run example project (converting xls table to html).
