Hi, bro
I have to convert xlsx to xls, so choose your library.
After execute cli "go mod tidy", it is different col.go between "github" and "pkg.go.dev".
Could you update source on "pkg.go.dev"?
Big Problem is different code compare to github when execute "go mod tidy".
Function is "func (xf *XfRk) String(wb *WorkBook) string", because of converting date format.
Thank you, bro. Happy new year ^o^
