Why is there an extra line at the end of the CSV export of a canned report?

Hello Netta,

We are using the Canned Report module in open source BI Helical Insight to create pixel perfect paginated reports. While exporting the report to CSV, we observe an extra blank line at the end of the file. What is the reason for this behavior, and is it expected?

Thank You,

Hello Netta,

As shown in the above screenshot, each record in the CSV file ends with a line break (LF). Because of this line-ending character, text editors like Notepad++ or EditPlus display an additional blank line at the end of the file.

This is standard CSV behavior and is expected when the last row also ends with a newline character. Most CSV generators add this by default to ensure proper file formatting and compatibility with Excel and other tools.

This extra line does not affect the data integrity or cause any issues while opening or processing the CSV in Excel or other applications. Please let us know if you face any issues due to this extra line in the CSV, so that we can look into it.

Thanks,
Helical Insight.
