JSON and CSV Conversion for Lightweight Data Workflows
A practical explanation of when to use JSON, when to use CSV, and how to convert between them safely.
JSON and CSV are both useful, but they represent data differently. JSON handles nested objects. CSV is a table.
Use CSV for rows
CSV works well for spreadsheets, exports, and simple records where each row shares the same columns.
Use JSON for structure
JSON is better for APIs, nested data, arrays, and objects with optional fields.
Convert with care
Nested JSON may need flattening before it becomes a clean CSV. Always check headers and missing values after conversion.
