What is a CSV file?
CSV is the lingua franca of tabular data: plain-text rows of comma-separated values that every spreadsheet, database and programming language can read. It holds exactly one sheet, with no formulas or formatting.
What is a JSON file?
JSON is the data format of the modern web: nested keys and values that every programming language parses natively. APIs speak it, apps are configured with it, and it stays readable, diffable text throughout.
Why convert CSV to JSON?
CSV can't hold multiple sheets, data types, formulas or formatting — and Excel easily mangles its encodings and dates. JSON is what APIs and JavaScript expect — structured, nestable and parseable in one line of code.
