JSON is more flexible for programming, APIs, and modern databases.

CSV works well for spreadsheets, but JSON is better for code.

Handle headers, delimiters, quotes, and escape characters properly.

Most CSVs use commas, but sometimes tabs or semicolons are used instead.

Format JSON with clean indentation so logs, payloads, and fixtures are easier to read.

Convert JSON arrays to CSV format for spreadsheets, data analysis, and exports.

Check JSON syntax and catch parser errors before the payload goes any further.
