Frequently Asked Questions
What CSV formats are supported?
We support all common CSV formats including RFC 4180 compliant CSV, tab-delimited (TSV), semicolon-delimited, and custom delimiter formats. We handle quoted values, escaped quotes, and multi-line cells.
How are empty cells handled?
Empty cells in CSV are converted to null values in JSON. You can choose to keep them as empty strings or convert them to null/none based on your requirements.
Can I convert large CSV files?
Yes! Our tool can handle files up to 5MB, which is typically tens of thousands of rows. For larger files, we recommend using desktop CSV tools or splitting the file.
What about special characters and encoding?
We support UTF-8 encoding and handle special characters, emojis, and international text properly. The tool automatically detects and preserves character encoding.
Can I convert JSON back to CSV?
While this tool converts CSV to JSON, we have a separate JSON to CSV converter tool available on our website for reverse conversion.
Is my data secure?
Absolutely! All conversion happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
