FAQ
What CSV format is supported?
Standard comma-separated values with the first row as headers. Values containing commas or quotes should be enclosed in double quotes.
Can I use a different delimiter?
Currently the tool supports comma-separated values. Tab-separated and semicolon-separated formats will be added in the future.
Is my data processed on a server?
No. All conversion happens entirely in your browser. Your data never leaves your device, ensuring complete privacy.
Does the first row need to be headers?
Yes. The first row of your CSV is used as JSON object keys. Each subsequent row becomes an object with those keys.
Can I convert CSV with custom delimiters?
This tool uses the standard comma delimiter. If your data uses semicolons, tabs, or pipes, you may need to find-and-replace to commas first before converting.
