You’re right to be careful in this regard, as importing one large VCF file into CRM or Outlook often does not work. The best option is to split and organize your contacts before importing them.

The best option for this is to use a reliable "Split VCF Tool" like the "OSTtoPSTAPP Split vCard Tool." This tool can be used to split a large VCF file into smaller files so that the CRM or Outlook can import them without any issues.

This VCard Split Tool also retains the details available in the VCF file. This includes the name, email address, phone number, and even images. This vCard Split Tool is used to split any version of the vCard because it supports 2.1, 3.0, and 4.0 versions, which makes it suitable for use with all platforms and CRM tools.

This is due to the fact that this vCard Split Tool supports offline usage. This ensures that your details are safe during the process. This offline vCard Split Tool is also a lightweight tool, so your system will not hang or lag. It is virus-free and works perfectly with Windows 11, 10, 8.1, 8, 7 and others.

One of the tips that you may find useful is that you should divide the contacts into smaller batches. This should be between 50 to 200 contacts per file. Also, ensure that you name the file correctly. This would be of great use to you.

In order to have a clean and error-free import experience, you should use a structured VCF file splitting method.
