Curso de Microsoft Power BI desde cero | IMPORTAR DATOS DESDE ARCHIVO CSV (video 4)
Importing Data into Microsoft Power BI
Introduction to Importing Data
- The video begins with an introduction to the course on Microsoft Power BI, focusing on how to import a file from a device for data analysis.
- The presenter navigates to the "Get Data" option in the ribbon and selects the type of file to import, specifically a CSV file.
Selecting and Opening the File
- The user selects a CSV file named "Titanic" and opens it, initiating the data import process.
- A window appears showing options related to delimiters used in the CSV file; commas are identified as separators between columns.
Understanding Delimiters and Data Separation
- The system automatically separates data into columns based on comma delimiters but notes that some fields (like names) may not be separated correctly due to their structure.
- Other delimiter options are available, such as equal signs or semicolons, which can also be used for column separation.
Data Type Detection
- Power BI identifies data types for each column based on initial rows; passenger IDs are recognized as integers while survivor status is treated as text.
- Users can choose whether to analyze only the first 200 rows or the entire dataset, with implications for processing time.
Finalizing Import Settings
- Once satisfied with settings, users click "Load" to import data directly into Power BI, establishing connections within the model.
- After loading, users can view imported tables in a grid format and access all previously seen fields through clicks.
