Regex - Link formatting

问题

I have the following link in excel:

http://en.wikipedia.org/wiki/Melon_Bicycles

I would like to retrieve the link as: http://en.wikipedia.org

In google doc I used: =REGEXEXTRACT(A1; "https?:\/\/(.[^\/]+)"), whereas A1 is the cell with the unformated link.

Any recommendation how to implement that in excel 2010?

回答1:

A simple approach would be to use LEFT with FIND. Something like this

=LEFT(A1,FIND("/",A1,9))
