What these tools are for
They cover the jobs that come up when you build on top of search: choosing a SERP API and estimating the bill, checking what a request actually returned, building localized Google URLs, and making sure crawlers can reach the pages you want indexed. The text tools handle the list work in between: removing duplicates, comparing two lists, splitting and joining lines, and pulling columns out of a CSV.
Tools that only transform text, like the JSON formatter, the list tools or the 2FA code generator, run entirely in your browser. Tools that need to reach another site, like the header checker, send one request from our server and return the result without storing it. The search API tester forwards your key to the provider you picked and nowhere else.
