  • I have a column in google sheets with ZIP codes. How do i put a column next to it that will automatically fill with what city is associated with that zip code?
    I have seen this request pop up quite a few times. I did a quick search for free APIs of zipcode lookups. This one, named "zipcodestack" (I'm not in any way tied to, endorsing, or promoting them) seemed like a pretty good resource with up to 10,000 free lookups each month. So, I wrapped a quick script around it and made it a custom sheets function called GET_CITY:. Source: about 3 years ago
