If some phone numbers or emails disappear after converting Gmail CSV contacts to VCF, it’s usually because of field mapping or format issues. Gmail CSV files have multiple columns, but VCF files store this data using specific tags. If the converter doesn’t match these correctly, some details won’t transfer.
Another reason is that some converters only export primary contact fields and ignore secondary phones or emails. Using an older vCard version can also cause missing information.
To avoid this, check your CSV headers and mapping settings before converting and use a tool that supports all fields.
From my experience, using Softaken CSV to vCard Converter worked smoothly — it kept all my phone numbers and emails intact and made the process simple.
