Help us understand the problem. What is going on with this article?

ExcelのN関数がちょっと便利。込み入ったif関数を書かなくてよくなる。

More than 3 years have passed since last update.

A列とB列が一致していたら、1
不一致だったら、0

みたいな判定をするときに、
=if(a1=b1,1,0)
て書いてました。

これをn関数を使うと
=n(a1=b1)
と書き換えられます。

ちょっとだけ便利です。(ただ可読性は下がります)

ついでに、
=n(a:a=b:b)
でも同じ結果になります。
