GO：使用GOLANG中的https://github.com/tealeg/xlsx库解析Excel数据的字节数组

I want Parse byte array of excel data using https://github.com/tealeg/xlsx library in GOLANG. Actully i am getting data from the request(as byte array) to my GRPC server where I have to parse and process it.

I checked library API but it accepts file name as parameter.

"github.com/tealeg/xlsx"

func main(){
xlsx.OpenFile("file.xslx")
}

Any idea how do I pass byte array directly and process the same.
