How to export to xlsx in Go?

Question

go

On Go, you need to write out the upload in xlsx, the upload is very heavy for an example on the server, such an upload on php eats 60 gigs of RAM. All this needs to be optimized. Advise a Go solution so that it unloads to excel without reading the entire file into memory, but adding new lines.

Answer 1

ssconvert csv -> xlsx

Answer 2

I wouldn't switch from php to go just for this.
It's easier to upload to csv, then convert via libreoffice

Answer 3

It is better to use not xlsx, but csv or even a tab-separated file.
Go has Reader and Writer for such tasks, which do not write and read the entire file at once, in parts.
