How to Avoid Corrupted Contact Entries When Importing Thunderbird Contact Data Into iCloud

[Tim_David]

Corrupted contacts usually happen when Thunderbird exports data in a format iCloud can’t fully read. CSV files from Thunderbird often have headers or encoding that don’t match iCloud, and even Thunderbird’s vCard export may include unsupported fields. The result is scrambled names, broken phone numbers, or missing emails once you import into iCloud. A simple fix is to convert your Thunderbird contacts into a clean vCard file first. Softaken CSV to vCard Converter makes this easy. It can convert CSV contacts to VCF accurately, preserve every detail, and even handle bulk CSV to vCard conversion. Once converted, you can import the VCF into iCloud safely, without corrupted or incomplete entries.
