Frequently Asked Questions
Yes. Both formats are produced in a single streaming pass — no need to convert twice. Download JSON, download XML, or copy either format directly from the output panel.
Yes. Parsing and conversion run in a dedicated Web Worker with chunked streaming. Files of any size work — including 500MB+ CSVs — with no UI freeze and no upload.
No artificial limit. Unlike upload-based converters that cap at 10–50MB, this tool processes locally — your system memory is the only constraint.
The first row is automatically used as column headers, becoming JSON keys and XML element names. If your CSV doesn't have headers, you can override with custom field names.
Yes. Switch between Table view (spreadsheet-style) and Code view (raw JSON or XML) from the toolbar at any point during conversion.
All conversion runs locally in your browser via a Web Worker. Your data — including any PII or sensitive columns — never leaves your device.
