Frequently Asked Questions
Is my data uploaded anywhere?
No. The conversion runs entirely in your browser using JavaScript. Your CSV data never leaves your device.
What CSV format is supported?
Standard comma-separated values with a header row. Quoted fields are supported. The first row is used as JSON keys.
Can I convert large CSV files?
Yes — since processing is local, there's no server file size limit. Performance depends on your browser, but files up to tens of MB convert fine.
