Avoid loss of data by previewing mappings and looking for hidden characters within Excel prior to conversion. I used Softaken Excel to vCard Converter as it has a mapping preview and detects duplicates. During Batch Excel to vCard Conversion, it logged rows with errors so that I could rectify them and re-run conversion on these entries alone. Organize phone numbers and remove special characters from names to avoid converting issues. After exporting, try out some vCard files on target devices. The process of Convert Excel to vCard retained all critical fields and minimized manual cleanup time, saving time and providing safe imports today.
