Removing Empty Lines at the End of a CSV File Generated from an XLSX Source in Azure Data Factory

When using the Copy Data Activity in Azure Data Factory to convert an XLSX file to a CSV file, you might encounter an issue where an empty line is added at the end of the resulting CSV file. This can be problematic when you need a clean and accurate CSV file. Fortunately, there are several solution-oriented approaches to address this problem.

Solution 1: Utilize Data Flows for Enhanced Control:

1. Create a Data Flow activity in Azure Data Factory.
2. Configure the source of the Data Flow to read the CSV file generated by the Copy Data Activity.
3. Add a Source transformation in the Data Flow to extract the CSV data.
4. Apply any necessary transformations or data manipulations, including removing the empty line.
5. Add a Sink transformation to write the transformed data back to a new CSV file.
6. Configure the Sink transformation to overwrite the original CSV file or specify a different location as needed.
7. Execute the Data Flow activity to generate the CSV file without the empty line.

Solution 2: Filter out the Empty Line:

1. Use the Copy Data Activity to create the CSV file from the XLSX source.
2. Implement a subsequent transformation step using a script or custom code to filter out the empty line.
3. The script should read the CSV file, exclude the empty line, and rewrite the updated data to a new CSV file.
4. Configure the script to overwrite the original CSV file or specify a different location.

By employing either the enhanced control provided by Data Flows or implementing custom code to filter out the empty line, you can successfully remove the unwanted empty line at the end of the CSV file generated from an XLSX source in Azure Data Factory. These solution-oriented approaches ensure that you have a clean and accurate CSV file for your data processing needs.
