What is a CSV ↔ JSON Converter?

This tool converts between CSV (spreadsheet) and JSON formats. Import CSV data and get structured JSON, or convert JSON arrays back to CSV for use in Excel or Google Sheets. Headers are automatically detected and mapped.

Frequently Asked Questions

Does it auto-detect CSV delimiters?

It supports comma, semicolon, and tab delimiters.

Can I convert nested JSON?

Flat JSON arrays convert best. Deeply nested JSON is flattened using dot notation.

Is my spreadsheet data private?

Yes. All conversion runs locally in your browser.
