Can manual CSV to VCF conversion handle thousands of contacts efficiently?

In my experience, manual conversion is not practical for thousands of contacts. becuase It takes too much time and often creats data mismatch problem and fails to load in other platforms. When I faced this issue, I searched for many reliable tools on Google and ChatGPT to solve CSV to VCF Conversion issues, and after that i found an offline GainTools CSV to VCF Converter software, which worked much better because it supports bulk conversion and completes the task quickly without losing contact details.
