I need a clean, up-to-date CSV that lists every real-estate agency operating in the city of São Paulo. Start with the official CRECI-SP search (https://crecisp.gov.br/cidadao/buscarporimobiliaria) and use Google or any other reliable source to fill in anything the registry is missing so the final list is as complete as possible. The file must be saved in standard, comma-separated UTF-8 format and include these mandatory columns for every record: • Agency name • WhatsApp number (international format, digits only) • Email address You may add extra fields such as street address or website if you capture them, but the three columns above have to be populated for every single row. Acceptance criteria • All agencies returned by the CRECI-SP search for the city of São Paulo are present. • No duplicate rows. • Random spot checks against the source site confirm accuracy of contact details. • File opens in Excel without further cleaning. Please deliver a single .csv file when finished.
