Sebagai analis bisnis, materi ini benar-benar mengubah cara saya bekerja dengan data. Dulu saya butuh berjam-jam membersihkan data manual, tapi setelah belajar Power Query, prosesnya jadi otomatis dan rapi. Bagian dashboard Power BI paling saya suka karena akhirnya saya bisa menyajikan angka mentah menjadi insight yang gampang dipahami atasan. Rumus Excel modern seperti XLOOKUP juga dijelaskan dengan contoh nyata. Sangat direkomendasikan untuk siapa pun yang ingin presentasi datanya lebih meyakinkan.

This course finally made pivot tables click for me in a way years of using Excel at work never did. The transition into Power BI feels smooth because it builds on the same data cleaning habits taught in the Excel section. I walked away able to build a dashboard I'd actually be comfortable presenting to management.

Mình làm việc với Excel khá lâu nhưng toàn dùng công thức cơ bản, học xong khóa này mới thấy mình bỏ lỡ nhiều thứ hay ho như hàm INDEX MATCH hay cách xử lý dữ liệu lộn xộn cho gọn gàng. Phần chuyển sang Power BI được sắp xếp rất tự nhiên, không bị rời rạc với phần Excel trước đó. Điểm mình thích nhất là dữ liệu ví dụ trong bài khá thực tế, không phải kiểu số liệu đẹp sẵn như trong sách giáo khoa, nên áp dụng vào công việc thực tế dễ hơn nhiều. Sau khóa học mình đã tự làm được một dashboard báo cáo doanh số cho phòng mình mà trước đây phải nhờ người khác làm hộ. Cảm giác tự tin hơn hẳn khi phải làm việc với số liệu lớn.

ปกติใช้ Excel แค่พื้นฐาน พอมาเรียนคอร์สนี้เข้าใจสูตรที่ซับซ้อนขึ้นเยอะ โดยเฉพาะการทำ Pivot Table กับข้อมูลที่ยุ่งเหยิงจริงๆ ไม่ใช่ตัวอย่างสวยๆ ที่จัดมาแล้ว ส่วนของ Power BI ก็สอนตั้งแต่การเชื่อมข้อมูลไปจนถึงทำแดชบอร์ดที่ดูเป็นมืออาชีพ ชอบที่แต่ละบทมีแบบฝึกหัดให้ลองทำตามจริง ไม่ใช่แค่ดูอาจารย์ทำ พอเรียนจบเอาไปปรับใช้กับรายงานยอดขายที่บริษัทได้ทันที รู้สึกว่ามั่นใจเรื่องการวิเคราะห์ข้อมูลมากขึ้นเยอะ

Les formules Excel avancées expliquées ici m'ont vraiment débloqué au travail, même si j'aurais aimé un peu plus de temps sur Power BI.

สอนสูตร Excel ได้ละเอียดดีมาก แต่ส่วน Power BI อยากให้มีตัวอย่างเคสธุรกิจเพิ่มอีกหน่อย

Excelの関数からPower BIでの可視化まで流れがつながっていて分かりやすかったですが、ダッシュボード作成の部分はもう少し丁寧な説明が欲しかったです。

A parte de tabelas dinâmicas junto com Power BI mudou completamente a forma como eu monto meus relatórios no trabalho.

I came into this with decent Excel skills but almost no exposure to Power BI, and the course does a great job bridging the two. The early modules on cleaning messy datasets with formulas like INDEX/MATCH and pivot tables were a solid refresher, and then it builds naturally into building actual dashboards in Power BI. What I appreciated most was that every example uses a realistic messy dataset instead of clean textbook numbers, so the techniques actually transfer to real reports. By the end I put together a sales dashboard for my team that would have taken me days to figure out on my own before this.
