Accuracy is a mix of software logic and data discipline. Even the best converter cant fix badly structured Excel files, but good software minimizes damage. Accurate tools validate headers, respect data types, and prevent field overlap during export.

An effective Excel to vCard converter also previews results before final conversion, which reduces surprises. Tools like Softaken Excel to VCF Converter are often evaluated on this point because they combine file validation with user-controlled mapping. What this really means is fewer missing contacts and less cleanup after import, especially with large datasets.
