Batch remove trailing whitespace from each line in a large number of TXT files

After system export or manual editing of a large number of TXT plain text files, many trailing spaces may be generated. These blank parts can cause file parsing errors or data processing issues, and the trailing spaces can make the text look messy and disorganized, affecting the browsing and reading experience. By removing trailing spaces, the text can be made more standardized and tidy, facilitating reading, parsing, and storage. Below is an introduction on how to batch remove trailing spaces at the end of each line in many TXT notepad files at once, supporting various text formats: TXT, JSON, HTML, XML, SRT, CSV.

1. Use Cases

Here, you can batch delete the trailing whitespace content at the end of each line in Notepad files to optimize document resources and improve document tidiness.
