Frequently Asked Questions
This tool supports three major data formats: JSON (JavaScript Object Notation), CSV (Comma-Separated Values), and XML (Extensible Markup Language). You can convert between any combination of these formats — that is 6 conversion directions in total.
Nested JSON objects are automatically flattened using dot notation for CSV output. For example, {"address": {"city": "NYC"}} becomes the CSV column address.city with value NYC. Nested arrays are serialized as JSON strings within the CSV cell.
Yes, you can upload .json, .csv, .xml, and .tsv files using the "Upload File" button. The file contents are read locally in your browser and loaded into the input area for conversion.

Absolutely. All conversions happen 100% in your browser using JavaScript. Your data is never sent to any server, never stored, and never logged. This is a fully client-side tool — you can even use it offline once the page has loaded.
Yes, since all processing is done in your browser, performance depends on your device. Most modern browsers can handle files up to several megabytes without issues. For very large files (10MB+), you may experience a brief delay during conversion.
