### 3/5 — バックアップのcsvファイルが取込めない

*2023-09-20, version 1.6.4*

バックアップしたcsvファイルをExcelでインポートすると、「このテキスト ファイルのデータは、1つのワークシートに入りきりません。」のエラーが出て全連絡先が取込めません。エラーの原因はcsvファイルの改行コードがLFになっていると思われます。これを修正するにはWordでcsvファイルを開き、読み込みに使用するエンコードはその他のUnicode(UTF-8)で取り込んだ後、ファイルの変換で行末を改行(CR)/改行文字(LF)にて保存します。拡張子がtxtになるのでcsvに変更するとインポート出来るようになります。
