Let's say I have column A:A containing titles. In another column I want to show the first letter of title, ignoring special characters, like so:
| Title | Chapter |
|---|---|
| (A) Title | A |
| Title | T |
This is an array formula put on B1 I made so far, but not working properly as my example above:
=ARRAYFORMULA(if(row(A:A)=1,"Chapter",REGEXEXTRACT(A:A,".")))
It contains an error message #N/A on every row if column A doesn't have text. It also shows a special character if it begins with. This is how it currently looks:
| Title | Chapter |
|---|---|
| (A) Title | ( |
| Title | T |
| #N/A | |
| #N/A |
Any ways to fix this?
