CSV Encoding

CSV is the lingua franca of bulk data handoffs: analysts pull product exports into Excel, finance teams hand off daily order reports as .csv files, and partners ship inventory updates as comma-separated rows. Go's standard library ships encoding/csv, a small, no-frills package that reads and writes CSV without trying to be clever about it. This lesson covers the Reader and Writer types, their configuration knobs, how to map between records and structs by hand, and the streaming patterns that make large files tractable.
