Format Details
CSV
CSV (Comma-Separated Values) is a plain-text tabular data format that uses commas to delimit column values and line breaks to separate rows. It is one of the most universally supported data interchange formats, readable by any spreadsheet application, database, or programming language. CSV is ideal for exporting and importing data between different systems due to its simplicity, human readability, and near-universal compatibility.
JSON
JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format derived from JavaScript object literal syntax. It natively supports objects, arrays, strings, numbers, booleans, and null, allowing it to represent arbitrarily nested data structures. JSON has become the universal standard for REST API responses, configuration files, and data interchange on the web, with native parsing support in virtually every programming language.
