Hi, I need you to build an app for me that exactly like this one:
[url removed, login to view]
But with the option of batch upload / entering URLs.
So for instance, a user has equivalent URLs in an Excel sheet, just enters / uploads them in the app, selects the languages and countries for them using the selector, and generates the correct hreflang tags.
It could be a PHP script with an upload option, or an Excel / GDocs sheet with batch entering.
I need the script ready in 3 weeks.
