When converting spreadsheets into contact files, preserving international characters and phone labels is essential for global use. Simple converters often strip accents or treat all numbers as generic text, which leads to broken contact details. Tools that handle extended character sets and maintain labeled fields such as mobile, home, or work perform significantly better. Desktop solutions with manual field mapping and version compatibility usually produce the most reliable VCF output. In user discussions, Softaken Excel to VCF Converter is frequently mentioned because it supports Unicode encoding and allows accurate tagging of phone types before export. These capabilities ensure that contacts with non-Latin names and region-specific formats remain intact across devices.
