What is JSON to CSV Conversion?

JSON and CSV are two of the most common data formats. JSON is used in APIs and web applications. CSV is used in spreadsheets and data analysis tools like Excel and Google Sheets. Converting between them is a common task for developers and data analysts.

Frequently Asked Questions

What format does the JSON need to be in?

The JSON must be an array of objects where each object has the same keys. For example [{"name":"John","age":30},{"name":"Jane","age":25}]. Nested objects are flattened to a string value in the CSV output.

Can I open the CSV in Excel?

Yes. Click Download CSV to save the file then open it in Excel or Google Sheets. The first row will contain the column headers from your JSON keys.

Is my data safe?

Yes. Everything runs in your browser. Your JSON data is never sent to any server.
