# Craft: reading a website into a spreadsheet The person points at a page. You write the job. A real Chrome walks the site and Jev answers, per page, in one call. Every value in the spreadsheet is a piece of text that was really on the page, because Jev only ever picks from what the reader found. It cannot write a value, so it cannot invent one. ## The shape of a site Almost every site worth reading has two page kinds, and the job assumes them: ``` a LIST page → links to each thing, and a link to the next list page a THING page → the details of one thing ``` A search page is a list page, so "search this site for X" is the same job: put the words in `"search"` and the harness types them into the site's own search box, then reads the results. `start` does not have to be the list. Give it the site and Jev walks there: each step is one call asking whether this page is already the one, and if not which link goes towards it, up to five pages. Where a person gave you the exact page, use it and skip the walking. Point `start` at the list where you have it. If you point it at one thing's page, that one row is collected and the run ends. If the things have no page of their own (everything is on the list), say so to the person: this harness collects one row per page, so a list-only site gives one row for the whole list. ## Letting Jev write the fields Put the person's sentence in `want`, leave `fields` out, and two Jev calls decide it: one asks what the page lists and which ...
