How to Convert JSON to CSV

JSON is the standard format for APIs and web data, but spreadsheets and CRMs expect CSV. Manually converting between them is tedious and error-prone, especially when objects have different fields or nested structures.

Our free JSON to CSV converter handles this automatically. Paste a JSON array of objects, and the tool extracts all unique keys as column headers, then maps each object to a row. Missing fields become empty cells, and values containing commas or quotes are properly escaped per CSV standards.

Common use cases: exporting API responses to Excel, converting database query results for analysis, transforming web-scraped JSON data into importable lists, and preparing data for tools that only accept CSV. Everything runs in your browser for complete privacy.

Frequently Asked Questions

What JSON format does it accept?
+
An array of objects, like [{"name":"John"},{"name":"Jane"}]. A single object also works and becomes one row.
How are nested objects handled?
+
Nested objects and arrays are converted to JSON strings within the cell. For deeply nested data, consider flattening it first.
What if objects have different fields?
+
The tool collects all unique keys across all objects as columns. Objects missing a field get an empty cell for that column.
Are commas in my data handled correctly?
+
Yes. Values containing commas, quotes, or line breaks are automatically wrapped in quotes and escaped per the CSV standard.
