Frequently Asked Questions (FAQ)
Quick answers to your questions about data security, conversion compatibility, and more.
Will my VCF or Excel file be uploaded to the server?
Absolutely not. The core advantage of Excel2VCF is that data is processed entirely within your local browser. File content never leaves your device, ensuring the highest level of data privacy and security.
What should I do if the imported contacts show garbled Chinese characters?
Garbling typically occurs during the Excel/CSV to VCF process. Please ensure your original CSV file is saved with **UTF-8 encoding**. Our tool generates VCF files in UTF-8 by default, which is the standard method for resolving Chinese character garbling. If the problem persists, try reopening the CSV in Excel, saving it as UTF-8, and then re-uploading.
After VCF to Excel conversion, some fields like 'Notes' or 'Multiple Phones' are missing?
Our tool's parser is designed to identify and extract all standard and non-standard fields in VCF.
- For **multiple identical fields** (e.g., two mobile numbers), we will either merge them into the same cell or create separate columns in Excel (e.g., 'Phone 1', 'Phone 2').
- If your VCF contains non-standard data, please send the VCF file to us for analysis, and we will update the parsing logic to support that field as soon as possible.
Are there limits on file size or the number of contacts?
Since conversion is performed locally, file size mainly depends on your device's performance (CPU and memory). Theoretically, there are no strict limits, but processing VCF files containing over **50,000 contacts** may take a significant amount of time, so please be patient.
