Very​‍​‌‍​‍‌​‍​‌‍​‍‌ often, large CSV files make online converters crash since such services generally have size limits or their servers get slow when processing a big amount of data. If you change CSV to VCF for mobile phones, CRM, or email clients, a bulk file needs more stable processing. A desktop CSV to vCard converter tool can handle large datasets without going silent because it does all the work locally. The majority of users who have huge contact lists, such as business directories or CRM exports, are likely to choose vCard 3.0 or 4.0 since these versions are better at managing structured data. Moreover, advanced converters give an option of correct field mapping so that even large files can retain the correct format. By means of a tool like GainTools CSV to vCard Converter, you can be sure that all the 8,000+ contacts will be done quickly without the occurrence of duplicates or missing data. Testing a small sample file to be certain of the formatting before the actual import into mobile phones is always the best practice. That way, you can prevent errors of mass importing that necessitate a time-consuming cleanup later ​‍​‌‍​‍‌​‍​‌‍​‍‌on.
