Regular Expression in Google Apps Script

I believe we all have used Regular Expression while working on different projects in different languages. Basically we Regular Expressions to match a pattern of characters. Here in this post we will see how you can define Regular Expression in Google Apps Script.

Importance of Regular Expression(RegEx) and why you should learn:

• RegEx helps you to shorten your code.
• Helps you in pattern matching to validate text input.
• It works with almost all programming language.

 

Here’s below code implementation of Regular Expression(RegEx) in Google Apps Script:

 

function RegularExp() {
  var string = "Hello World, Welcome to Weird Geek 2019";
  var regExp = new RegExp("([a-z]+\\s[a-z]+\\,\\s[a-z]+\\s[a-z]+\\s[a-z]+\\s[a-z]+)","gi"); 
  var lastName = regExp.exec(string)[1];
  Logger.log(lastName); 
}

Basically in above code we have a string in Line 2 for which we have to define a RegEx and finally match it. In 3rd line we have define the RegEx where [a-z]+ is to matches a characters, \\s is for space. And finally we in line 4th we executed the pattern matching with the string via RegEx. Here, as a output we will get Hello World, Welcome to Weird Geek as we do not want the digit included in the link.

If you want the digits then just add [0-9]+ in the Regular Expression we defined in line 3rd line.
