Anyone who has used Google Tag Manager has at least heard of the GTM dataLayer. The dataLayer has many functions, but one important one is the ability to access any dom element on the page and reveal its value. This can be extremely handy when you want to send data to tracking software like Google Analytics. The difficulty comes in actually finding these values.
Say you wanted to find what a user typed into a field when someone submits your form or clicks somewhere else on a page. Using the dataLayer, you can find any value you want associated with another event; however, you have to go and manually find it. Introducing GTM dataLayer Sifter, a chrome extension that automatically shows the dot notation path from one element to another. Its purpose is to make analyzing content and finding variables within the dataLayer much simpler.
