What input does JSON-to-CSV support?
JSON arrays (recommended) and single objects; nested objects flatten to parent.child fields, arrays serialize to JSON strings.
Can the CSV open in Excel?
Yes — open or import directly; field names become headers and data aligns in rows for analysis.
How are nested fields handled?
Nested objects expand to parent.child columns (e.g. user.name), keeping complex data structured.
Is online conversion safe?
Safe — runs locally, data never uploads, suitable for business data and API responses.
What is it best for?
API export, data analysis, Excel processing, reports, migration and cleaning.
Are there limits on free use?
No. Free, no registration, unlimited, large JSON supported.
Can I download the file?
Yes — one-click .csv download, or copy the table content.
Are special characters handled?
Yes — commas, quotes and newlines auto-escape to prevent column shifts.
