I'm using tealeg xlsx library to read an excel file https://github.com/tealeg/xlsx . They have documentation here https://godoc.org/github.com/tealeg/ . It works perfectly fine if I call the
OpenFile() by local directory, but I wanted to use an
http.Request.FormFile() return object which is of type
multipart.Form. How do I use this file to be read by the tealeg package?
OpenReaderAt() looks like something I should use, but the multipart. Form object returned from
http.Request.FormFile() returns a file interface but I'm not sure how to access the readerAt object? https://golang.org/pkg/mime/multipart/#File
