谷歌表格查找和替换正则表达式

Question

I cannot seem to get a regexp to work in the find and replace box in my Google Sheet. I am trying to remove all of the - characters in any cell. Cells often look like this

-something
-some other stuff
-more things that-are-here 

So I want it to end up like

something
some other stuff
more things that-are-here 

I cannot even tell if this regexp thing supports RE2 properly.

Supposedly this should match all - characters and support multi line. But it does not. It only removes the first - in each cell.

Answer 1

You can try

(?<=\n|^)-

Here's the test result

• (?<=...) Positive looksbehind
• \\n|^
  • \\n line break
  • | or
  • ^ start of the string
• - matches - literally
