JSON to CSV

The JSON to CSV converter turns an array of JSON objects into a tabular CSV file ready for spreadsheets. It is completely free and requires no sign-up, so you can export API data for analysis without any setup. Data analysts, marketers, and developers preparing reports use it to move structured data into Excel or Google Sheets.

What does JSON to CSV do?

JSON to CSV inspects an array of JSON objects, collects the unique keys across all objects, and uses them as column headers in the output file. Each object then becomes one row, with its values placed under the matching column. Because CSV is inherently flat, nested objects and arrays are typically flattened or serialized into a single cell so no information is silently discarded.

How to use JSON to CSV

1. Paste a JSON array of objects into the input panel.
2. Review the auto-detected column headers generated from the object keys.
3. Download or copy the resulting CSV file.

Key features

• Automatic header detection from JSON object keys

Frequently asked questions

Is JSON to CSV free to use?

Yes, JSON to CSV is completely free with no sign-up required. You can convert unlimited files for spreadsheet analysis or reporting.

What happens to nested JSON objects during conversion?

Nested objects and arrays are flattened or serialized into a single cell value since CSV has no native support for hierarchy. This keeps every row complete even when the source data includes complex nested fields.

Does it work if some objects have different keys?

Yes, the converter merges all unique keys found across the array into one consistent header row. Objects missing a particular key simply receive an empty cell in that column.

Can I open the exported file directly in Excel?

Yes, the downloaded CSV file opens directly in Excel, Google Sheets, or any spreadsheet application. The comma-separated format is standard and requires no additional import steps.
