Frequently Asked Questions
What file formats are supported?
Currently, we support CSV (Comma-Separated Values) files with UTF-8 and GBK encoding. The tool automatically detects common delimiters like commas, semicolons, and tabs.
Is there a file size limit?
Yes, the maximum file size is 10MB. This ensures optimal performance while handling most common CSV files. For larger files, consider splitting them into smaller chunks.
Is my data secure?
Absolutely! All data processing happens entirely in your browser. Your files never leave your device, ensuring complete privacy and security. No data is uploaded to our servers.
Can I use this tool offline?
Once loaded, the basic functionality works offline since all processing is client-side. However, you need an internet connection to initially load the application.
How do I handle encoding issues?
If special characters are not displaying correctly, try saving your CSV file with UTF-8 encoding before uploading. Most spreadsheet applications have this option in their save dialog.
