Frequently Asked Questions

What is JSON to CSV conversion?

JSON to CSV conversion transforms data from JSON (JavaScript Object Notation) format into CSV (Comma-Separated Values) format. This is useful when you need to import JSON data into spreadsheet applications like Excel or Google Sheets.

What does flattening do?

Flattening converts nested JSON objects and arrays into a flat structure with dot-notation keys. For example, an object with nested address becomes separate columns like address.city and address.zip, making it compatible with spreadsheet formats.

Can I use different delimiters?

Yes! You can choose between comma, semicolon, or tab as your delimiter. This is useful when your data contains commas or when working with different regional CSV formats.

How are arrays handled?

Arrays are flattened with index-based keys. For example, an array of tags becomes tags.0, tags.1, tags.2, etc. Each array element gets its own column in the CSV output.

Is this tool free to use?

Yes, our JSON to CSV Converter is completely free, with no registration and no limits.

What happens to my data?

We do not collect or store what you enter.

Can I download the CSV file?
