JSON to CSV
JSON to CSV works best when records share a stable shape that can flatten into consistent columns. If arrays, nested objects, or optional fields vary too much, the export becomes messy fast, so this page focuses on planning the column layout before you generate a CSV for teams and imports.

FAQ
What makes JSON hard to convert to CSV?
Nested objects, arrays, and inconsistent record shapes are the main issues because CSV expects a flat and regular table.
Should every JSON field become a CSV column?
Not always. It is usually better to keep only the fields that help reporting, review, or import workflows.
Why inspect the CSV after a JSON export?
A quick review helps catch sparse columns, repeated headers, awkward field names, and missing values before the CSV is shared or imported.
