Frequently Asked Questions

What CSV format is supported?

The tool supports standard CSV format with comma-separated values. The first row should contain headers, and subsequent rows contain data. Quoted values with commas are handled correctly.

How are numbers handled?

The tool automatically detects numeric values and converts them to numbers in the JSON output instead of keeping them as strings.

Can I convert CSV with quotes and commas?

Yes, the tool properly handles values enclosed in quotes, including those containing commas. This follows standard CSV escaping rules.

What if my CSV has empty values?

Empty values are converted to empty strings in the JSON output. The tool preserves the structure even with missing data.

Can I use this for large CSV files?

The tool works in your browser, so very large files may be slow. For best performance, use files under 1MB. For larger files, consider using server-side tools.
