Replace Values & Fill Columns in Excel Power Query For Data Cleaning:
In Excel Power Query, Replace Values lets you quickly fix or update specific data entries, while Fill Columns (Down or Up) fills missing cells using nearby values — both essential for smooth and complete datasets. #ExcelTips #PowerQuery #DataCleaning #ExcelTutorial #ExcelSkills #DataPrep

Hệ sinh thái LLaMA đang bùng nổ, nhưng đâu là mảnh ghép còn thiếu? Nhiều người cho rằng đó là các công cụ chuẩn bị và chú thích dữ liệu, vốn vẫn là một nút thắt cổ chai thủ công lớn cho việc tinh chỉnh mô hình. Bạn nghĩ sao?
