on Google Sheets to fetch publish date information from a URL (A1, in the formula). We would like to do something similar on AT but I can’t for the life of me figure out how AT would write this out as a formula.
Airtable formulas cannot fetch information from a url. They can only do computations based on values in other fields in the same record (or in a linked record).
You may be able to use scripting to fetch data from a url.
