Frequently Asked Questions
How are headers handled?
The first row of your CSV data is treated as the header row, which defines the JSON keys for the resulting objects.
Does it support numbers?
Currently, all values are treated as strings to preserve formatting (like phone numbers with leading zeros). You can parse them as numbers in your application logic.
Is it secure?
Yes, the conversion runs entirely in your browser using JavaScript. Your data never leaves your device.
