Frequently Asked Questions
Does the first row need to be headers?
Yes. The converter treats the first row as property names for the JSON objects. If your CSV does not have headers, you should add them manually before converting.
What delimiters are supported?
The converter supports comma-separated values by default, which is the standard CSV format. Most spreadsheet exports use commas as delimiters.
Can I convert large CSV files?
Yes. The tool handles CSV files of typical sizes (up to a few MB) without issue since all processing runs locally in your browser. Very large files may take a few extra seconds.
Is my data sent to a server?
No. All conversion happens entirely in your browser. Your CSV data is never transmitted to any external server and remains completely private on your device.
