Perguntas Frequentes

Tudo o que você precisa saber sobre o JSON para Excel.

How are nested objects handled?

Nested objects are automatically flattened using dot notation (e.g., user.address.city becomes a distinct column header).

Are arrays inside objects supported?

Yes, arrays are stringified into a single cell to ensure your data fits perfectly into an Excel grid.

Is my data uploaded to a server?

No. Everything is processed 100% locally in your browser memory via JavaScript and WASM. Your data never leaves your machine.

Is there a file size limit?

Yes. The free tier limits files to 10MB to ensure smooth local browser performance. Refinata Pro users can process massive files up to 200MB.

What's the difference between this and JSON to CSV?

While both flatten data, this tool generates a native Excel (.xlsx) file with proper data types, whereas CSV is pure comma-separated text.

How is this different from online JSON-to-CSV tools like ConvertCSV or JSON2CSV?

Most online converters upload your file to a server for processing, which is a privacy risk for sensitive data. Refinata processes everything locally. Additionally, most tools fail on deeply nested JSON or API wrapper objects — Refinata's auto-detection handles both gracefully. The live table preview also lets you verify the output before downloading, which other tools lack.
