❓FAQ
Q: What is the difference between Objects and Array conversion?
A: Objects mode uses the first row as keys (if 'First row is header' is checked) and creates an array of objects. Array mode simply converts each CSV row into an array, creating a 2D array structure.
Q: Can I convert large CSV files?
A: Yes! All processing is done in your browser, so file size is limited only by your device's memory. However, very large files (100MB+) may take longer to process.
Q: Does it handle quoted fields correctly?
A: Yes, our parser correctly handles CSV fields enclosed in double quotes, including fields with commas, newlines, or quotes inside them.
Q: Is my CSV data secure?
A: Absolutely! All conversion happens locally in your browser. Your data never leaves your device, ensuring complete privacy and security.
