Why use ConvertWiki?
Turn API JSON into spreadsheet rows
JSON is flexible for APIs, but CSV is easier to inspect in spreadsheets, reporting tools, and database import screens. This converter works best with arrays of objects because each object becomes one row and each property becomes a column.
Nested objects are flattened with dot notation so fields remain readable instead of being dropped. That makes the output easier to filter, sort, and review before you import it somewhere else.
Typical workflows
- Export an API response into Excel, Numbers, or Google Sheets.
- Flatten nested JSON for a quick audit or data cleanup pass.
- Create CSV files for imports, reports, or one-off handoffs.
Frequently Asked Questions

Special characters are handled automatically. Values containing commas or quotes are wrapped in double quotes.
Check your JSON for missing commas, unclosed brackets, or unquoted keys. Use the JSON Formatter tool to validate it first.
