From Chrome Developer Console, highlight elements to get JavaScript code. Built by: Triangle Digital (triangledigital.xyz)/r/nGTM Variable Builder:

This tool can be used to highlight a portion of a website (text only), a product ID, a price, or the name of a page. Then click the icon for the extension. You can view the output of what you highlighted by going to the JS console in Chrome.

Run your generated JavaScript in the console. You should copy the generated javaScript function into a custom Google Tag Manager variable if it returns what you highlighted.
