Deleting all blank lines in plain text TXT files is typically used to enhance file compactness and readability. For instance, when file content needs to be imported into databases or processed by programs, blank lines may cause parsing errors or waste storage space. In log files or configuration files, blank lines can also add unnecessary length, interfering with information retrieval and analysis. Therefore, removing redundant blank lines helps simplify content structure while improving document professionalism and consistency. The following describes how to bulk delete all blank lines from a large number of TXT plain text files, supporting multiple text formats such as TXT, JSON, HTML, XML, SRT, and CSV.
1. Use Cases
When multiple people collaboratively edit many TXT note files, different habits often lead to many blank lines being added. After the file content is completed, a unified format is needed. At this point, we can batch remove these blank lines to streamline the content and improve processing efficiency.
