Begin by opening the Excel file from which you want to extract data. Ensure that the data is organized in a single worksheet, as each worksheet will need to be saved separately if you have multiple.
Before exporting, review the data to ensure there are no merged cells, complex formulas, or hidden rows/columns that may affect the CSV format. Simplify the dataset to plain text and numbers for optimal results.
In Excel, navigate to the top-left corner and click on the 'File' menu to access the file options. This menu provides access to various file operations, including saving and exporting.
From the 'File' menu, choose the 'Save As' option. This option allows you to save the current Excel file in a different format, including CSV.
In the 'Save As' dialog, select the location where you want to save the file. In the 'Save as type' dropdown menu, choose 'CSV (Comma delimited) (*.csv)'. This format is suitable for most CSV needs, but there are other CSV options if your data requires them (like CSV UTF-8).
Enter a name for the CSV file in the 'File name' field. Ensure it is descriptive and appropriately indicates the contents or purpose of the data. After naming the file, click 'Save'. Excel will alert you that certain features may be lost in the CSV format; confirm by clicking 'OK'.
Open the newly created CSV file using a text editor or a spreadsheet tool to review its contents. Ensure that the data is correctly formatted and that no information is missing. Check for any anomalies due to the conversion process, such as misplaced commas or unexpected line breaks.
By following these steps, you can efficiently transfer data from an Excel file to a CSV file without using any third-party tools or integrations.
FAQs
What is ETL?
ETL, an acronym for Extract, Transform, Load, is a vital data integration process. It involves extracting data from diverse sources, transforming it into a usable format, and loading it into a database, data warehouse or data lake. This process enables meaningful data analysis, enhancing business intelligence.
What is ELT?
ELT, standing for Extract, Load, Transform, is a modern take on the traditional ETL data integration process. In ELT, data is first extracted from various sources, loaded directly into a data warehouse, and then transformed. This approach enhances data processing speed, analytical flexibility and autonomy.
Difference between ETL and ELT?
ETL and ELT are critical data integration strategies with key differences. ETL (Extract, Transform, Load) transforms data before loading, ideal for structured data. In contrast, ELT (Extract, Load, Transform) loads data before transformation, perfect for processing large, diverse data sets in modern data warehouses. ELT is becoming the new standard as it offers a lot more flexibility and autonomy to data analysts.
