About CSV
CSV (comma-separated values) is the universal format for spreadsheets and data exports. The first row holds column names and each following row is one record.
Private by design
Developer data is often sensitive: API responses, tokens, customer records, internal configs. This CSV Viewer processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
