Most free tools fail with large CSV files , but Softaken CSV to VCF Converter handles them easily. I had a 10,000-contact CSV file from my business list and it converted the entire thing in one go without errors. The software is built for bulk conversion and does not freeze or skip records. It also keeps the order and structure of data intact. You can map and preview everything before exporting , which helps you avoid mistakes. It works on all Windows versions and saves a lot of time . Try the demo on a smaller file first and then use the full version for large data.
