Frequently Asked Questions
What delimiter should I use?
Use comma for standard CSV files, semicolon for European-style CSV (common in Excel exports), tab for TSV files, or pipe for custom formats.
What if my CSV has no headers?
Toggle off 'First row is header'. The JSON output will use numeric keys (0, 1, 2...) for each column.
Can this handle large CSV files?
Yes, this tool processes CSV in the browser. Very large files (100MB+) may be slow depending on your device.
