Converting JSON to CSV without hiding nested data

CSV works best when each JSON object represents one row with the same fields. Before using JSON to CSV, decide how arrays and nested objects should be represented: separate columns, multiple rows, or a second file.

Convert a small sample first. Check column order, quoted commas, line breaks, blank values, and whether numbers remain distinguishable from text. Keep the original JSON for anything the flat export cannot express faithfully.

Which nested field needs to survive the conversion?
