Split column data after last delimiter into new column - google-apps-script

Question

I have the following data example in a google sheet:
url
https://www.testwebsite.com/compute/v1/test/images-prd-5d4d/glob/images/testimage-vsfd
https://www.testwebsite.com/compute/v1/test/images-prd-5d4d/glob/images/testimage-sdawr|
What I need is to extract the data after the substring "images/" and have something like this:
url
extract
https://www.testwebsite.com/compute/v1/test/images-prd-5d4d/glob/images/testimage-vsfd
testimage-vsfd
https://www.testwebsite.com/compute/v1/test/images-prd-5d4d/glob/images/testimage-sdawr|testimage-sdawr
I have created the following function to get this but is only extracting everything after the last "-":
function strip() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName("Sheet6");
const vs = sh.getRange(2,1,sh.getLastRow() - 1).getDisplayValues().flat();
let vo = vs.map(s => [s.match(/\b[0-9A-Zaz/]+$/gi)[0]]);
sh.getRange(2,2,vo.length,1).setValues(vo);
}
What is the proper way to extract the data it's mentioned above?

Answer 1

You could use this on Apps Script:
function strip() {
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName("Sheet6");
const vs = sh.getRange(2,1,sh.getLastRow() - 1).getDisplayValues().flat();
const string= "/images/";
for (i = 0; i < vs.length; i++){
//Using substrings:
const extract = vs[i].substring(vs[i].indexOf(string) + string.length);
sh.getRange(i+2,2).setValue(extract);
//Using .split():
// const extract = vs[i].split(string); //This splits the string in 2.
// sh.getRange(i+2,2).setValue(extract[1]); //Adding the second part of the array;
}
}

If you want to do it like a custom function you can try the following code:
function strip(url) {
var text = url;
var splittedValue = text.split("/images/");
return splittedValue[1];
}
It would work something like this:
Input:
Result:
The script can also be changed to get a specific range of data automatically so that every time you add a new URL you get the result in the next column automatically, but this is just for you to get the idea.

Answer 3

Say your URLs are in A2:A. You can use
=arrayformula(if(isblank(A2:A),,substitute(REGEXEXTRACT(A2:A,"/images/[A-Za-z0-9-_|/\.]+"),"/images/","")))
Use native formulas where possible. That is more efficient.
If you already dealt with the issue with run time delay, and have a need to use custom function for other reasons, you can match with the "/image/" part and then remove it, or, alternatively, specifying a capturing group. Also don't forget other value characters such as _, |.
