Remove brackets in Google sheets using Regex

If you are using Google sheets, you might want to remove the content within brackets. It is very easy to do it using regular expressions.

Fore example if you have content such

I am Johnnymac[133]

and you want to remove the bracket and numbers within.

Do these in your google sheet.

1. Edit > find and replace
2. Select regular expression match
3. Enter the regular expression \[[0-9]+\]
4. Click replace all

The result would be

I am Johnnymac

Hope this helps. This took me hours to figure out.
