Die Übungen mit den unordentlichen Tabellen waren genau das, was ich im Büroalltag brauche, und die Erklärungen zu Duplikaten und Textfunktionen saßen sofort.

Bonne remise à niveau sur le nettoyage de données, l'explication des filtres avancés est claire, seul bémol le rythme accélère un peu vers la fin.

По работе мне постоянно прилетают таблицы в ужасном состоянии, с лишними пробелами, дублями и разнобоем в форматах. Этот курс наглядно показал, как привести такой хаос в порядок с помощью современных функций и автоматизации. Особенно пригодился раздел про разделение и объединение данных в столбцах, раньше я делал это вручную. Часть про удаление дубликатов тоже сэкономила кучу времени. Хотелось бы чуть больше про работу с очень большими массивами, но это мелочь. В целом мой рабочий процесс стал заметно быстрее.

এলোমেলো স্প্রেডশিট পরিষ্কার করা এখন সহজ লাগে, তবে ডুপ্লিকেট সরানোর অংশটা আরেকটু গভীর হলে ভালো হতো।

Полезно, но местами суховато.

Les astuces pour nettoyer rapidement des colonnes remplies d'espaces et de doublons m'ont fait gagner un temps fou au bureau.

Eu trabalho com planilhas bagunçadas praticamente todo santo dia e esse curso mudou completamente minha forma de organizar dados. As aulas sobre remover duplicatas, padronizar textos e usar tabelas dinâmicas são bem diretas, sem enrolação. Gostei especialmente da parte de formatação condicional para identificar erros rapidamente. O ritmo é bom, nem muito rápido nem arrastado, e dá pra acompanhar mesmo tendo pouco tempo livre. Depois de duas semanas já consegui limpar uma planilha de estoque que estava um caos há meses.

Khóa học hướng dẫn dọn dẹp dữ liệu khá dễ hiểu, chỉ tiếc là phần xử lý dữ liệu trùng lặp hơi lướt qua nhanh.

Excel'deki karmakarışık tabloları nasıl düzenli hale getireceğimi hiç bilmiyordum. Kurs adım adım, gerçek örneklerle anlatıyor ve pivot tablolara geçmeden önce temel temizlik tekniklerini çok net gösteriyor. Ofisteki raporlarımı artık çok daha hızlı hazırlıyorum.
