Empty fields normally will not lead to conversion failures, however, they have the potential to produce VCF files that look messy and are incomplete. The reason is that those who export contacts from Excel to VCF might find that there are some parts in their contact apps that are blank. It is by getting rid of the duplicate empty rows or columns that one can make sure that the output is cleaned. There are tools that only map the filled fields which makes this task much easier. While performing the Excel to vCard conversion, the OSTtoPST App Excel to vCard Converter is the tool that facilitates the process by allowing users to ignore empty data, hence, they can convert Excel to vCard in a proper way without having any kind of mess.
